The MS-13 and 18th Street Gangs: Emerging Transnational Gang Threats?

Summary
Two predominantly Latino gangs, Mara Salvatrucha (MS-13) and the 18th Street gang (M-18),
have raised concern among policy makers for a number of reasons, including (1) membership in
these gangs has spread from the Los Angeles area to other communities across the United States;
(2) these gangs are considered “transnational,” primarily because MS-13 and M-18 cliques are
being established in Central America and Mexico; (3) there are reports suggesting that these
gangs are engaged in criminal enterprises normally associated with better organized and more
sophisticated crime syndicates; and (4) MS-13 and M-18 gang members may be involved in
smuggling operations and, by extension, could potentially use their skills and criminal networks
to smuggle terrorists into the United States. To date, however, no evidence exists establishing a
link between MS-13 and M-18 members and terrorists.
Nevertheless, some observers maintain that these two gangs may develop the capacity to become
organized criminal enterprises capable of coordinating illegal activities across national borders.
Yet, others find them to be no more criminally organized or sophisticated than other street gangs.
At issue for Congress is whether the MS-13 and M-18 gangs constitute an emerging transnational
criminal threat.
The federal response to the MS-13 and M-18 gang problem has largely involved the enforcement
of criminal and immigration laws, including the deportation of alien gang members. More
recently, federal efforts have focused on prosecuting gang members under the Racketeer
Influence and Corrupt Organizations (RICO) statute. Deported alien gang members have
established MS-13 and M-18 gang cliques in their home countries, and some experts suggest that
U.S. deportation policies have effectively transported U.S.-styled gang culture to parts of Central
America and Mexico. Moreover, evidence shows that deported alien MS-13 and M-18 gang
members have established a “revolving door” migratory pattern of repeat illegal reentry into the
United States, raising concerns that these “migratory” alien gang members may become involved
in narco-trafficking, smuggling, and other criminal activities along the U.S.-Mexico border.
This report will be updated periodically.

The MS-13 and 18th Street Gangs: Emerging Transnational Gang Threats?

Introduction
Street gangs have long been a concern to policy makers. The more recent emergence, growth, and
expansion of two Latino street gangs, the Mara Salvatrucha (MS-13)1 and the 18th Street Gang
(also known as the Mara 18 or M-18), have raised concern among policy makers for several
reasons.2 First, membership in these gangs has spread from the Los Angeles area to other
communities across the United States. Second, there are concerns that these gangs are becoming
increasingly transnational, primarily because MS-13 and M-18 cliques are being established in
Central America3 and Mexico. Third, there are reports suggesting that these gangs are
increasingly engaged in criminal enterprises normally associated with better organized and more
sophisticated crime syndicates. Fourth, and perhaps most disturbingly for policy makers in a post-
9/11 world, alarms have been sounded in some circles that international terrorist organizations
like al-Qaeda could exploit alien and narcotics smuggling networks controlled by these gangs to
infiltrate the United States. To date, however, no evidence suggests that these gangs and
international terrorist groups are cooperating with one another.4 Nonetheless, at issue for
Congress is whether the MS-13 and M-18 gangs constitute an emerging transnational criminal
threat.
This report provides an overview of the MS-13 and M-18 gangs,5 examines how MS-13 and M-
18 gangs are different from other gangs and organized crime groups, and discusses what
constitutes a transnational gang. The report also explores whether MS-13 and M-18 gangs are
transnational gangs, and discusses the various federal responses to these gangs. The report
concludes with a discussion of selected issues that may be of interest to Congress.
Defining the Issue
There is no single definition of what characteristics constitute a transnational gang.6 Various
characteristics have been used to distinguish and identify transnational gangs, including (1) gangs
that are criminally active and operational in more than one country; (2) gangs that are involved in
criminal activities committed by gang members in one country that may be planned, directed, and
controlled by gang leaders in another country; (3) gangs that tend to be mobile and adapt to new
areas; and (4) the criminal activities of such gangs tend to be sophisticated and transcend national

1 The word mara is a Spanish word for a gang, and marero means gang member. These terms are more commonly used
in El Salvador. In the recent literature on Latino transnational gangs, the term maras has come to refer specifically to
the MS-13 and M-18 gangs.
2 Although there are other domestic gangs with transnational members, MS-13 and M-18 are the focus of this report
because they have been the most prominently discussed by the media and policy makers.

5 This report addresses the domestic aspects of the MS-13 and M-18 gangs. The international perspective on these and
other gangs in Latin America is beyond the scope of this report. For information on the international perspective, see
CRS Report RL34112, Gangs in Central America.
6 Transnational gangs are not a new phenomena in the United States and have included gangs composed of members of
Asian, Russian, African, Serbian, Bosnian, Jamaican, and other races, ethnicities, and nationalities. Some of these
transnational gangs have evolved into highly organized and sophisticated criminal enterprises known for influencing
government officials and the judiciary in the countries in which they operate. In the United States, the most well-known
example of this type of crime syndicate is the Mafia, or La Cosa Nostra, composed of members of Sicilian descent.

borders. For a gang to be considered transnational, the gang would likely exhibit more than one of
the aforementioned characteristics; however, with respect to the MS-13 and M-18 gangs, much of
the literature characterizes these gangs as transnational because they are present and criminally
active in more than one country.
Background on the MS-13 and M-18 Gangs
Two predominantly Latino gangs, MS-13 and M-18, have taken a place on the national policy
agenda, as membership in these gangs has spread from Los Angeles to other parts of the United
States. Although street gangs are largely an urban phenomenon, MS-13 and M-18 cliques have
emerged among disaffected Latino youth in suburban and rural areas across the country.
According to a national gang survey, the MS-13 and M-18 gangs have an established presence in
Washington DC; Northern Virginia; certain cities in Maryland; Nashville, Tennessee; New York,
New York; Houston, Texas; and other rural and urban areas.7 The M-18 gang is a much larger
gang than the MS-13 in terms of overall membership, with approximately 30,000 to 50,000
members nationwide, compared with 8,000-10,000 MS-13 members nationwide in 2009;8
however, the MS-13 gang has generated greater media coverage and congressional attention.9
Federal law enforcement authorities have targeted MS-13 and M-18 alien gang members for
deportation, an action that some argue has contributed to the development and proliferation of
U.S.-styled gangs in Central America and Mexico.10 Although membership in the MS-13 gang is
largely Salvadoran and membership in the M-18 gang is largely Mexican, both gangs have
recruited members in the United States from other Central American countries. Some have argued
that as a result of this inter-mixed membership, both gangs have established gang cliques in El
Salvador, Honduras, Guatemala, and Mexico that are modeled on, and perhaps linked to, U.S.
MS-13 and M-18 gangs.11 According to some, Central American and Mexican MS-13 and M-18
gangs maintain elements often referred to as “LA-style” gang culture commonly found among
Los Angeles-based gangs.12 Because the gangs are present in multiple countries, some contend
that these gangs are transnational.

9 Although it is unclear whether the MS-13 gang engages in more violent or different types of criminal acts than M-18
or other gangs, MS-13 cliques are reported to have presence in almost every state. According to Federal Bureau of
Investigation (FBI) estimates, the MS-13 gang is active in 42 states and the M-18 gang is active in 20 states. U.S. DOJ,

bandanas or certain sports jerseys; using gang-specific identifying hand signs; getting gang-identifying tattoos; using
gang-specific graffiti to mark a gang’s territory; participating in gang-specific initiation practices, often referred to as
getting “jumped-in” or “beaten-in,” where initiates are beaten by current gang members for a specified length of time
or in a particular way; and being required to commit a violent criminal act in order to prove one’s loyalty to the gang.

The MS-13 and 18th Street Gangs: Emerging Transnational Gang Threats?

Origins of Mara Salvatrucha (MS-13)
The MS-13 gang reportedly originated in Los Angeles in the 1980s. During this period, thousands
of Salvadorans fled the civil war in their country.13 By the end of the 1980s, some estimates
indicate that more than 300,000 Salvadorans had settled in Los Angeles.14 One hypothesis on the
gang formation asserts that Salvadorian immigrants during this period banned together and
formed the MS-13 gang.15
MS-13’s early membership is reported to have included former guerrillas and Salvadoran
government soldiers whose combat experience during the Salvadoran civil war contributed to the
gang’s notoriety as one of the more brutal and violent Los Angeles street gangs.16 Moreover, the
gang developed a widely reported reputation of employing unusual methods of violence,
including using machetes in gang attacks.17 Despite the gang’s reputation, sources in law
enforcement indicate that little evidence exists to substantiate that the MS-13 gang is more violent
than other street gangs.18
Origins of 18th Street Gang (M-18)
The 18th Street gang (M-18) was originally formed by Mexican migrants in the 1960s in the
Rampart neighborhood of Los Angeles who were blocked from joining other native-born
Mexican-American gangs.19 The 18th Street gang grew by expanding its membership to other
nationalities and races, and it was among the first multiracial, multiethnic gangs in Los Angeles.20
Are MS-13 and M-18 Different from Other U.S. Street Gangs?
According to research, gangs can be characterized as either first-generation, second-generation, or
third generation.21 First-generation gangs are characterized as traditional street gangs. These

gangs are turf-oriented and localized, lack sophistication, engage in unsophisticated criminal
activities, and tend to have a loose leadership structure. First-generation gangs participate in
“opportunistic criminal activity and intergang rivalry.”22
Second-generation gangs are characterized as having an organized structure similar to a business.
They tend to “assume a market rather than a turf orientation.”23 Second-generation gang activities
tend to be drug-centered. Moreover, these gangs tend to operate in broader areas and have a
centralized leadership.24
Third-generation gangs are characterized as highly sophisticated, “mercenary-type group[s] with
goals of power or financial acquisition and a set of fully evolved political aims.”25 Third-
generation gangs tend to operate in a global environment and “may embrace quasi-terrorism or
true terrorism” to advance their goals.26
Most urban gangs fit into the first- and second-generation characterizations.27 Some researchers
believe, however, that the MS-13 and 18th Street gangs in some Central American countries have
some of the characteristics of a third-generation gang.28 Although such researchers do not link the
MS-13 and 18th Street gangs to terrorist groups, they assert that these gangs and terrorist groups
have some similar characteristics, such as having “a propensity for indiscriminate violence,
intimidation [and] coercion [that] transcend[s] borders, and target[s] nation-states.”29
In the United States, the MS-13 gang does not appear to have escalated to a third-generation
gang; however, evidence suggests that the gang’s presence in multiple states, as discussed above,
and its criminal activities indicate that the gang is evolving. This point is underscored by the 2004
National Drug Intelligence Center (NDIC) threat assessment report. Despite the generally loose
organization of the MS-13 gang, the NDIC’s 2004 report warned that the gang was increasing its
coordination between chapters in Los Angeles, Washington DC, Northern Virginia, and New
York, perhaps indicating efforts to create a national command structure.30

Criminal Enterprises

gang exists, and the lines between street gangs, transnational gangs, and organized criminal

enterprises can be blurred. The following section highlights some of the major distinctions
between these criminal groups.
How Are Transnational Gangs Different from Street Gangs?
Generally, most researchers agree that the primary distinction between transnational gangs and
other domestic street gangs is that transnational gangs are criminally active and operational in
more than one country. In some cases, they may be characterized as gangs in which members in
one country typically commit crimes that could have been substantially planned, directed, and
controlled by the gang’s leaders in another country.31 Other researchers characterize transnational
gangs as “very mobile, highly adaptable to new geographic areas, and [maintaining] connections
in their native countries.”32
As previously mentioned, most street gangs are either first- or second-generation gangs.
Transnational gangs, however, share some of the same characteristics as a third-generation gang.
For example, transnational and third-generation gangs tend to operate in a global environment—
that is, their criminal activities transcend borders. Moreover, with respect to their criminal
activities, both types of gangs tend to have a level of sophistication that closely resembles
organized criminal syndicates.
What Is an Organized Criminal Enterprise?
Organized crime is defined by the Federal Bureau of Investigation (FBI) as any group having a
formalized structure whose primary objective is to obtain money through illegal activities.33 Such
groups tend to have a vertical hierarchy, strong leadership, sanctions for failure of its members to
abide by codes of loyalty, and a level of entrepreneurial expertise. The specific criminal acts that
organized criminal enterprises tend to engage in are specified in statute as part of the Racketeer
Influenced and Corrupt Organizations (RICO)34 and the Violent Crimes in Aid of Racketeering
(VICAR)35 statutes. According to the FBI, organized criminal enterprises maintain control of their
illegal activities through tactics such as actual or threatened violence, graft, and extortion. The
activities of organized crime syndicates can be sophisticated enterprises capable of adversely
effecting localities, regions, and, in some cases, the nation as a whole.
How Are Street Gangs Different from Organized Crime?
With the exception of third-generation gangs, street gangs are generally considered distinct from
organized criminal enterprises because they typically lack the hierarchical leadership structure,
organizational structure, capital, and manpower required to run a sophisticated criminal

enterprise. Street gangs are generally more horizontally organized, with lots of small cliques with
their own leadership and no centralized, overarching leadership setting strategy and enforcing
discipline. Most often, gang leaders are easily and quickly replaced by other gang members
without disruption to the gang’s activities.
Street gangs often engage in some of the same types of criminal activity as organized criminal
enterprises, but generally at much lower levels and not always strictly driven by entrepreneurial
objectives. Research indicates that most street gang crime tends to be opportunistic and
improvised. As previously discussed, street gangs tend to be concerned with issues such as
neighborhood territory or turf protection and maintaining respect for the gang and its members.
Another key difference between street gangs and organized criminal enterprises is evident when
comparing federal prosecutions of organized crime with federal prosecutions of street gang
offenses. In gang cases, the prosecution can face obstacles prosecuting these cases under the
existing RICO statute, which has been instrumental in hampering, if not dismantling, organized
criminal enterprises. Generally, when a federal criminal gang case is being developed for a RICO
prosecution, prosecutors must demonstrate that the crimes were committed or were connected to
the interests of a criminal enterprise.36 Although many cases against organized criminal
enterprises have been successfully prosecuted under the RICO statute, it is more difficult to
develop a RICO case against street gangs.
MS-13 Gangs and Organized Crime
The Washington Office on Latin America (WOLA)37 researched and interviewed MS-13 members
in the Washington DC area over a period of a year.38 As a result of the research, WOLA issued a
report in February 2007, in which it concluded that MS-13 and M-18 members in the Washington
DC area were not engaged in a systematic effort to become more involved in organized crime.
The report found that the area’s MS-13 membership was sizable, although the members’ criminal
activity was largely limited to petty theft and neighborhood extortion. The analysis of the MS-13
gang in the Washington DC area concluded that active gang “hot spots” existed, but that the
maras did not constitute a major public security issue.
In contrast to the WOLA report, law enforcement officials point to evidence that the Washington
DC area’s gangs are indeed criminally active and may show signs of increasing criminal
sophistication.39 For example, they assert that in the Washington DC area, Immigration and

36 To investigate and prosecute organized criminal enterprises, the FBI relies on the Enterprise Theory of Investigation
(ETI). Under this investigative model, the investigation and prosecution are focused on the criminal activities of the
entire criminal enterprise rather than on just those committed by any single individual. This approach targets all aspects
of the criminal operation to disrupt and ultimately destroy the entire structure of the enterprise. In fact, an essential part
of the ETI strategy is to show that the individuals in such an organization commit criminal acts “solely to benefit their
criminal enterprise.” Using the ETI, the FBI can support the prosecution of the criminal enterprise under RICO statutes
or its related statute, VICAR, and seize the enterprise’s assets to seriously disrupt or dismantle entire criminal
organizations.
37 WOLA is a non-governmental organization focused on democracy, human rights, and social and economic justice in
Latin America.

The MS-13 and 18th Street Gangs: Emerging Transnational Gang Threats?

Customs Enforcement (ICE) agents reported arresting 233 known violent gang members, 190 of
which were MS-13 members, in 2006. In addition, a milestone case for the federal prosecution of
gang members under the RICO statute was based on MS-13 members committing crimes in the
Washington DC area. Two MS-13 gang members were convicted of murdering six people and
attempting to kill four others in a federal case prosecuted in Prince George’s County, Maryland.40
The two convicted MS-13 members were part of an indictment brought against 22 MS-13
members. Successfully prosecuting a racketeering conviction against MS-13 members is seen by
some analysts as evidence that the gang’s criminal activities are becoming increasingly organized
and sophisticated.
Are MS-13 and M-18 Transnational Gangs?
As previously mentioned, MS-13 and M-18 gangs are generally considered to meet at least one of
the characteristics attributed to transnational gangs—they are present in more than one country.
And with respect to the MS-13 gang, evidence suggests that the gang is becoming more
organized, which is another characteristic of transnational gangs. For example, recent criminal
cases involving MS-13 defendants have included information and testimony that gang members
in Maryland were in telephone contact with other MS-13 members in cities across the country
and, on occasion, with MS-13 members in El Salvador.41 Criminal cases brought against MS-13
also indicate that the gang members share information and, in some cases, that cliques in one area
have loaned weapons to members of an MS-13 clique in another area.42 This evidence of contact,
communication, and perhaps criminal cooperation is seen by some experts as an indication that
the MS-13 gang could evolve from a street gang into a more sophisticated transnational gang.43
Some critics contend that the transnationalization of the MS-13 and M-18 gangs began with the
deportation of alien gang members from the United States in the mid-1990s. They assert that the
increase in deportations of aliens to Central America and Mexico initiated by changes made to
immigration law in the mid-1990s44 led to the establishment of MS-13 and M-18 cliques in those
countries. However, the actual number of alien gang members that were deported is not clear
from the immigration removal data. Others assert that these countries already had a gang problem
and that MS-13 and M-18 cliques were not formed in Mexico and Central American countries as
the result of a gang migration or as an effort to establish new gang franchises or otherwise further
gang-related criminal enterprises of the U.S.-based gangs.45 Instead, deported gang members
banded together for social and economic advantage, as a way to compete with existing Central
American and Mexican gangs, and to survive in a foreign environment on income obtained
through familiar criminal means. Once established, these MS-13 and M-18 cliques recruited new

local members, and their ranks continued to be supplemented with new native recruits and
additional U.S. alien gang deportees.46
Prevalence of MS-13 and M-18 Gangs in Central America
Estimates of the number of MS-13 and M-18 gang members in Central America and Mexico
range from 70,000 to 100,000, depending on the source of the information, and at least one report
claims that MS-13 and M-18 cliques have established a growing presence in 24 of Mexico’s 32
states.47 MS-13 and M-18 gangs in Central America and Mexico are reported to have larger total
memberships and are reportedly more structured than their U.S. counterparts, although these
differences are difficult to corroborate.48
Evidence of a Transnational Gang Threat?
Since the 9/11 terrorist attacks, attention has been focused on securing the U.S. borders and ports
of entry. The long, porous southern border with Mexico is considered a vulnerability, in part
because of the relative ease with which illegal aliens, narcotics, and contraband are smuggled into
the United States, as well as the extent to which people cross into the United States illegally.
Policy makers have been concerned about human and narcotic smuggling rings and the possibility
that such profit-driven enterprises could be used by terrorists to enter the country undetected.49
Although there is no data linking the MS-13 and M-18 gangs with organized smuggling activities,
there are concerns that the gangs may become more organized and sophisticated in their criminal
activities.
Federal Response to Gangs
In general, gang-related crimes fall within the jurisdiction of state and local law enforcement. As
gangs have spread across the country, and as their threat has become more national in nature, the
interest in finding adequate solutions to the problem has increasingly included all levels of
government. In the mid- to late1980s and early 1990s, Congress passed legislation federalizing
certain gang-related crimes and providing additional penalties for individuals convicted under
these laws.50 Moreover, in the mid-1990s, Congress passed legislation that changed immigration
enforcement laws and made more aliens deportable.51 In addition, the federal government has

taken an active role in helping state and local jurisdictions develop anti-gang responses through
support for research on gangs and through grant programs to help jurisdictions develop effective
gang prevention and intervention strategies.52
Two federal agencies are directly involved in the fight against gangs through the enforcement of
criminal and immigration laws. The Department of Justice (DOJ) administers the primary federal
efforts to investigate, apprehend, and prosecute domestic criminal gang activities. The
Department of Homeland Security (DHS) also plays a role through the enforcement of
immigration and criminal law. The following two sections discuss some of these DOJ- and DHS-
led initiatives. The sections do not discuss gang/crime prevention initiatives.53
Department of Justice Agencies and Initiatives
Several federal offices and bureaus within DOJ are engaged in fighting gang criminal activities.
For example, as the primary criminal investigative agency in the federal government, the Federal
Bureau of Investigation (FBI) is responsible for investigating criminal violations of federal law.
The Drug Enforcement Agency (DEA) is the lead agency charged with enforcing the controlled
substance laws and regulations of the United States. The agency is also charged with stemming
the production, manufacture, distribution and trafficking into the country of illicit drugs and, as
such, is the lead agency in several initiatives. In its role as federal prosecutor, the U.S. Attorney’s
Office (USAO) Criminal Division prosecutes federal gang cases investigated by the FBI and the
Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). In addition, the USAO Criminal
Division has a section known as the “gang squad,” which is a part of ATF-headed gang task force.
Because gang crime often involves the use of guns, the ATF is directly involved in investigating
both domestic and transnational gangs. These and other DOJ agencies also participate in anti-
gang task forces established to combat gang crime and various forms of international organized
crime, some of which specifically target transnational gangs.
FBI’s MS-13 National Gang Task Force
The FBI established the MS-13 National Gang Task Force (NGTF) in December 2004 to
coordinate the investigative efforts of federal, state, and local law enforcement agencies targeting
MS-13 gang members and their associates. By increasing and speeding the flow of intelligence
and information to support and coordinate investigative efforts, the MS-13 NGTF provides
information to help law enforcement agencies identify trends in gang activities.54
According to DOJ, the MS-13 NGTF is designed to manage the flow of information nationally
and internationally to help coordinate investigations. Reportedly, the FBI’s MS-13 NGTF works

reformed exclusion and deportation procedures. It consolidated exclusion and deportation into a single removal
process, expanded the definition of “aggravated felonies” to make more aliens subject to removal, and tightened the
standards for relief from removal. AEDPA expanded the class of crimes designated as aggravated felonies, which
would subject an alien to expedited removal.

with international law enforcement agencies to collect and share intelligence on transnational
gangs.55 The FBI has also launched the Central American Fingerprint Exploitation (CAFE)
initiative, which is designed to merge criminal records from Central American partner law
enforcement agencies with FBI fingerprint database to help identify gang members with criminal
histories.56 According to the FBI, more than 100,000 fingerprint cards (sets of fingerprints) have
been entered into the database, and of those, 20,000 cases have come to the attention of law
enforcement agencies in the United States.57
FBI’s Safe Streets and Violent Crimes Initiative
The Safe Streets and Violent Crimes Initiative (SSVCI) permits the Special Agent in Charge of
each FBI field division to establish long-term, proactive task forces focused on reducing violent
crime.58 The task forces place specific emphasis on the identification of major violent street gangs
and drug enterprises of national scope by applying the same methods used to successfully fight
traditional organized crime. According to FBI testimony before the Senate Judiciary Committee,
one of the first gangs to be targeted by the gang task force was the MS-13 gang.59 Moreover, the
work of the task force enabled the U.S. Attorney for the Central District of California to
successfully use statutes to prosecute the leaders of the 18th Street Gang and the Mexican Mafia.60
According to the FBI, the task force concept increases the effectiveness and productivity of
limited personnel and logistical resources, avoids duplication of investigations, and expands
cooperation and communication among law enforcement agencies. In response to the threat from
gangs, the FBI established the Safe Streets Violent Gang Task Forces (SSVGTF) to coordinate the
efforts of law enforcement at all levels of government and to use the same statutes, intelligence,
and investigative techniques against violent gangs that are used to fight organized crime. The
FBI’s Safe Streets and Gang Unit administers 160 task forces nationwide.61
FBI’s National Gang Strategy
The FBI’s National Gang Strategy (NGS) incorporates the investigative and prosecutorial
practices that have been successful in the Organized Crime/Drug Program National Strategy.62
The NGS promotes the sharing of information among federal, state, and local law enforcement
agencies, which in turn helps the FBI identify violent gangs with coordinated investigations that
support prosecutions. The NGS is a component of DOJ’s overall Anti-Violence Crime Initiative,

which is designed to promote cooperative strategies and information sharing on gang-involved
offenders among corrections, parole and probation, and law enforcement agencies.
FBI’s National Gang Intelligence Center
In 2005, pursuant to P.L. 108-447, Congress provided funding for the FBI to establish the
National Gang Intelligence Center (NGIC), a coordinating center for information and intelligence
on gangs that could be shared with law enforcement. According to testimony at a congressional
hearing, the NGIC “will enable the FBI and its local, state, and federal partners to centralize and
coordinate the national collection of intelligence on gangs in the United States and then analyze,
share, and disseminate” the information to the law enforcement community.63 Staffed with
intelligence agents, the NDIC provides law enforcement agencies with information on gang
growth, criminal activities, gang migrations, and emerging trends based on national and
international gang intelligence.64
Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)
The ATF is the principal law enforcement agency within DOJ responsible for enforcing federal
criminal laws and regulations relating to the firearms and explosives industries. Working directly
and in partnerships with other law enforcement agencies at all levels of government, the ATF
investigates and works to reduce crime involving firearms and explosives, act of arson, and illegal
trafficking of alcohol and tobacco products. ATF is the lead DOJ agency in the Regional Area
Gang Enforcement (RAGE) Task Force, which includes agents and officers from ATF, FBI, ICE,
and other state and local law enforcement agencies. In addition, ATF is the lead agency in the 15
Violent Crime Impact Teams (VCITs), 13 of which focus on gang activity tied to homicides.65
The ATF is also involved in several federal task forces and leads the investigations of violent
gang crime through its firearms tracing system and the National Tracing Center (NTC), as well as
through the Regional Crime Gun Centers (RCGCs) located in major cities plagued by gang
violence. The ATF also provides national training programs for federal, state, and local law
enforcement officers and prosecutors as part of the Project Safe Neighborhoods (PSN)66 program
on street-level gun recoveries, enforcement tactics, and firearms identification and tracing
procedures.
Gang Targeting Enforcement Coordinating Center
The national Gang Targeting Enforcement Coordinating Center (Gang TECC) is a unified federal
effort to coordinate anti-gang efforts among several DOJ agencies.67 Gang investigators from the
ATF, Federal Bureau of Prisons (BOP), FBI, U.S. Marshals, the DEA, and ICE share intelligence

to coordinate anti-gang investigations at the federal, state, and local levels. In addition,
investigative efforts are coordinated with prosecutors from the U.S. DOJ Criminal Division to
provide direct support, guidance, and assistance with anti-gang efforts.
DOJ Joint Initiative with El Salvador
In February 2007, the Attorney General announced an initiative to collaborate with the
government of El Salvador to fight transnational gangs operating in El Salvador, Central America,
and Mexico. The initiative, led by the FBI and the Department of State (DOS), provides
assistance to El Salvador’s civilian police (Policia Nacional Civil, or PNC). As part of the
initiative, a transnational Anit-Gang (TAG) unit was created to pursue and prosecute gang
members. The TAG units include investigators from the PNC in El Salvador, imbedded
prosecutors from El Salvador’s Attorney Generals office, special FBI teams assigned to El
Salvador, and support from DOS.68 FBI agents provide training, information sharing, and other
support to increase the capacity of PNC detectives to identify, arrest, and prosecute gang
offenders. In a second part of the initiative, the FBI will accelerate the implementation of the
CAFE initiative (described above), designed to improve the identification, tracking, and
apprehension of gang members.
Department of Homeland Security Agencies
Agencies within the Department of Homeland Security (DHS) also engage in federal anti-gang
initiatives. Efforts to deport alien gang members who reside illegally in the United States, or who
have committed certain crimes, are a significant part of ICE’s strategy. Customs and Border
Protection (CBP) leads the charge of enforcing immigration and criminal law at the border.
Immigration and Customs Enforcement (ICE)
ICE initiated Operation Community Shield in February 2005 to address the threat posed by the
MS-13 gang.69 This initiative was based on a 2003 ICE assessment of violent street gang activity
in the United States. The ICE assessment identified MS-13 as a street gang “having a presence
across the United States, a significant foreign-born membership and history of violence.70
The initiative was expanded to include other violent gangs. Under the expanded initiative, ICE
has investigated the violent criminal activities of several other gangs, including the 18th Street
gang. Since the initiative was launched, more than 15,000 gang members and associates have
been arrested, representing over 1,000 different gangs, of which more than 6,000 were criminal

arrests and 9,000 were administrative immigration arrests.71 In conjunction with the gang arrests,
ICE has seized 876 firearms (as of January 4, 2010).72
Customs and Border Protection
According to CBP, the MS-13 gang is engaged in smuggling drugs and illegal aliens, as well as
extortion, kidnapping, and murder for hire.73 The border patrol has been required to collect
intelligence information on the MS-13 gang since October 2004.74 In FY2006, the border patrol
apprehended 294 gang members nationally; of those, 208 were MS-13 members.75 Moreover, in
2006, the border patrol’s Rio Grande Valley sector (in Texas) had the highest number of MS-13
apprehensions nationally.76
Selected Issues for Congress
Whether the MS-13 and M-18 gangs pose a threat to the domestic security of the United States is
not definitively known. Moreover, with the exception of established MS-13 and M-18 cliques in
Central America and Mexico, it is not altogether clear whether these two gangs pose a particular
transnational threat. It is noteworthy, however, that despite the transnational aspects of the MS-13
and M-18 gangs—they are criminally active in more than one country—in many respects, they
are no different that other domestic street gangs. Nevertheless, MS-13 and 18th Street gang
members pose a criminal threat to the communities where they reside and conduct their criminal
activities. In addition, evidence suggests that previously deported members of these two gangs
reenter the United States illegally across the U.S.-Mexico border.
Criminal Prosecution of Gang Members
Federal efforts to dismantle and deter criminal street gangs include a number of approaches. One
approach to gang crime would lower the threshold for the number of individuals required to
constitute a “criminal street gang,” thus making it easier to apply additional charges to certain
felony offenses. Building on existing law, another response to the gang problem would impose
harsher prison sentences for gang-related federal felony offenses. This section will consider these
and other federal proposals to address the gang problem.
Sentencing Enhancements and Mandatory Minimums
Proposals have been made to permit or require (in the case of mandatory minimum sentences)
longer sentences for those convicted of certain serious federal crimes if they are committed by

gang members. Proponents of these types of anti-gang measures argue that such enhanced federal
penalties are needed to address the rising gang crime in communities across the country. They
contend that longer sentences could deter violent gang-related crime and encourage greater
cooperation by gang members with law enforcement and prosecutors—the rationale being that
gang members facing a longer prison sentence will be more inclined to cooperate with
prosecutors, providing useful information on the gang and its members in exchange for a shorter
prison sentence.77
Critics of harsher criminal penalties and mandatory minimum sentences argue against these
proposals on several fronts. On the broadest level, some critics oppose the further federalization
of laws that have been traditionally under the sole jurisdiction of states and localities. These
critics cite the growing number of new federal laws, recently estimated at almost 4,450.78 They
also argue that state and local law enforcement officers have the necessary experience and local
intelligence sources to investigate and prosecute gang crimes, which may vary greatly by state,
region, and locality, whereas federal sources are strained as they cope with investigating and
prosecuting national threats.79 Opponents of mandatory minimum sentences for gang-related
crime also point to the greater expense of imprisonment versus the costs of prevention and
rehabilitation efforts.80 Moreover, critics question the deterrence effect of these harsher penalties,
arguing that in certain situations, individuals break the law notwithstanding severe criminal
penalties.81 In addition, researchers have often noted that imprisonment can serve to strengthen
gang allegiances and function as criminal “finishing schools” for gang members.82
Gang-Specific RICO Act Provisions
Under current law, the RICO statute provides for prosecution in cases where the goal is to
effectively dismantle the criminal enterprise. As previously mentioned, federal prosecutors have
successfully prosecuted organized criminal syndicates under the RICO statute and have recently
sought the prosecution of several MS-13 gang members.
Proponents of expanding the federal RICO statute to include violent gang-related crimes argue
that having gang-specific RICO provisions is necessary to pursue violent gangs such as the MS-

13 and M-18 gangs. They contend that such provisions would provide law enforcement with an
important tool to investigate and prosecute gang-related crime. Moreover, they contend that gang-
specific RICO provisions will help federal prosecutors pursue gangs that have moved drug
trafficking and other criminal activity onto federal land to avoid detection and state or local
prosecution.
Opponents argue that existing RICO laws are sufficiently broad to provide for the successful
prosecution of gang-related crime. Despite the obstacles faced in developing successful RICO-
gang cases, gang members have recently been successfully convicted under existing federal
RICO statutes. The recent conviction of three MS-13 gang members in Hyattsville, Maryland,83
adds credence to the argument that existing RICO laws are sufficient. In addition, other gang
cases have been federally prosecuted under RICO statutes in the past, and several states have
enacted state-versions of RICO-like laws for prosecuting gang conspiracy cases.84
Immigration Enforcement and Border Security85
As previously discussed, one of the more overt tools used to dismantle gangs has been the
enforcement of immigration law. Because street gangs such as MS-13 and M-18 may have some
number of foreign-born members, immigration enforcement (i.e., deportation) is a direct method
for disrupting these gangs. ICE “sweeps” of alien gang members have netted both MS-13 and M-
18 members with criminal histories, as well as alien gang members without criminal histories.
Some critics contend that the gang problem cannot be resolved through immigration enforcement
alone. They argue that not all gang members are foreign nationals, and such a policy could lead to
ethnic and racial profiling. Furthermore, they assert that deportation is not a long-term solution to
the gang problem because evidence suggests that alien gang members are crossing illegally back
into the United States. They also argue that by deporting alien gang members, the United States is
deporting its gang culture to other countries.
Data Improvements on Transnational and Alien Gang
Data on gangs in general, and the MS-13 and M-18 gangs specifically, are limited. The
organizational strength of MS-13 and M-18 gangs across national borders, and their ability to
carry out serious criminal offenses, is an important indicator of their potential threat to the
domestic security of the United States. Currently, the National Youth Gang Center (NYGC)86

83 A federal indictment of 30 MS-13 members under existing RICO statutes recently led to the conviction of 3 gang
members, who could face sentences of life in prison or the death penalty. According to the superseding indictment of
June 4, 2007, the three defendants “conspired to participate in a racketeering enterprise in the United States and El
Salvador that involved murder, robbery, obstruction of justice, and witness tampering” as members of MS-13. For more
information, see Ruben Castaneda, “Two MS-13 Members Convicted of Racketeering,” Washington Post, November

authors a survey on youth gangs. While the survey includes responses from major law
enforcement jurisdictions (i.e., urban areas), it does not include every rural and suburban law
enforcement jurisdiction. As gangs spread to nontraditional areas in the country (i.e., rural and
suburban areas), the need to capture data in these areas becoming increasingly critical. More
detailed reporting of gang crime could help develop more refined information on the incidence of
such crime and the migration patterns of these gangs.
Conclusion
The concept of transnationalism was coined in the aftermath of the First World War in a
discussion of America’s composition as an immigrant “melting-pot” and the implications for
assimilation and maintaining a cultural connection to one’s previous homeland.87 More recently,
the concept of transnationalism has been used to describe the ideals of globalization, the free
movement of people, the sharing of culture, and improved communications across national
boundaries, and generally has been considered a positive concept. However, in the context of
crime policy, particularly after the terrorist attacks of September 11, 2001, transnationalism has
assumed a more ominous connotation, and the potential for gangs in the United States to become
transnational has become a concern to lawmakers.
The phenomena of gangs is complex, multifaceted, and constantly evolving. The allure of gangs
has traditionally been thought to be a response to issues associated with poverty and disparities in
social opportunities. Although gangs have always been in existence, gangs today are more
violent, more organized, and more widespread.
The problems associated with stemming the spread and sophistication of MS-13 and M-18 gang
activities may reflect current limitations to addressing what is now generally considered a
multinational and regional problem. The problems associated with these two gangs cannot be
solved by arrests, prosecution, imprisonment, and immigration enforcement alone. The fact that
these two gangs exist and operate outside of the United States and beyond the reach of domestic
law enforcement agencies indicates that domestic responses may not fully address the broader
problems presented by these gangs, and that a multilateral and multinational approach in
combination with domestic efforts may be warranted. Recent efforts of various federal agencies,
working together with the governments of other countries, particularly El Salvador, on their
problems with MS-13 and M-18 and other gangs, indicate that the federal response is moving
toward a bilateral approach to addressing the problem.
Whether the problem of these two gangs continues to be approached as a domestic social issue, a
domestic security issue, a multinational/regional issue, or a combination of these concerns has yet
to be determined. Congress may consider these and other issues in shaping a legislative response
to this complex policy concern.
