Law Enforcement and Technology: Using Social  January 11, 2022

Kristin Finklea 
As the ways in which individuals interact continue to evolve, social media has had an increasing 
Specialist in Domestic 
role in facilitating communication and the sharing of content online—including moderated and 
Security 
unmoderated, user-generated content. Over 70% of U.S. adults are estimated to have used social 
  
media in 2021. Law enforcement has also turned to social media to help in its operations. 
Broadly, law enforcement relies on social media as a tool for information sharing as well as for 
 
gathering information to assist in investigations. 
Social Media as a Communications Tool. Social media is one of many tools law enforcement can use to connect with the 
community. They may use it, for instance, to push out bulletins on wanted persons and establish tip lines to crowdsource 
potential investigative leads. It provides degrees of speed and reach unmatched by many other forms of communication law 
enforcement can use to connect with the public. Officials and researchers have highlighted social media as a tool that, if used 
properly, can enhance community policing.  
Social Media and Investigations. Social media is one tool in agencies’ investigative toolkits to help establish investigative 
leads and assemble evidence on potential suspects. There are no federal laws that specifically govern law enforcement 
agencies’ use of information obtained from social media sites, but their ability to obtain or use certain information may be 
influenced by social media companies’ policies as well as law enforcement agencies’ own social media policies and the rules 
of criminal procedure. When individuals post content on social media platforms without audience restrictions, anyone—
including law enforcement—can access this content without court authorization. However, some information that individuals 
post on social media may be restricted—by user choice or platform policies—in the scope of audience that may access it. In 
the instances where law enforcement does not have public access to information, they may rely on a number of tools and 
techniques, such as informants or undercover operations, to gain access to it. Law enforcement may also require social media 
platforms to provide access to certain restricted information through a warrant, subpoena, or other court order. 
Social Media and Intelligence Gathering. The use of social media to gather intelligence has generated particular interest 
from policymakers, analysts, and the public. Social media companies have weighed in on the issue of social media 
monitoring by law enforcement, and some platforms have modified their policies to expressly prohibit their user data from 
being used by law enforcement to monitor social media. Law enforcement agencies themselves have reportedly grappled with 
the extent to which they should gather and rely on information and intelligence gleaned from social media. For instance, 
some observers have suggested that agencies may be reluctant to regularly analyze public social media posts because that 
could be viewed as spying on the American public and could subsequently chill free speech protected under the First 
Amendment. 
At the federal level, there is no specific legislative framework that governs law enforcement use of social media. Rather, 
there are laws and policies governing law enforcement investigations and intelligence gathering broadly. Some observers, 
however, have questioned whether the nature of social media may place it in a qualitatively different category than law 
enforcement’s use of other investigative tools and have suggested that there should be enhanced boundaries with respect to 
law enforcement operations in these online spaces. For instance, some have suggested that law enforcement agencies should 
have written, publicly available policies on their use of social media; they should obtain local government approval before 
using these online spaces; they should obtain judicial approval for conducting undercover operations using social media; 
there should be restrictions on law enforcement contacting minors via social media; and law enforcement’s use of social 
media should be audited. Policymakers may consider these issues as they conduct oversight or debate legislation on law 
enforcement use of social media.

Law Enforcement and Technology: Using Social Media 
 
s the ways in which individuals interact continue to evolve, social media1 has had an 
increasing role in facilitating communication and the sharing of content online—
A including moderated and unmoderated, user-generated content. Law enforcement has also 
turned to social media to help in its operations. Broadly, law enforcement relies on social media 
as a tool for information sharing as well as for gathering information to assist in investigations. 
Over 70% of U.S. adults are estimated to have used social media in 2021, a substantial increase 
over the 5% of adults who were believed to use some form of social media in 2005.2 Similarly, 
according to a 2016 survey of law enforcement agencies by the Urban Institute (Urban) and the 
International Association of Chiefs of Police (IACP) on their use of social media, it “is becoming 
an increasingly popular tool that law enforcement agencies use.”3 Law enforcement agencies use 
this tool for purposes including engaging with the public and gathering evidence pursuant to 
investigations. In the Urban and IACP survey, respondents indicated that they use social media 
for a variety of purposes, the most common being to notify the community of public safety 
concerns (91%). They also reported using social media for community outreach and citizen 
engagement (89%), public relations and notifying the community of non-crime issues (86%), 
soliciting crime tips (76%), monitoring public sentiment (72%), intelligence gathering for 
investigations (70%), and recruitment and applicant vetting (58%).4 In addition, 60% of agency 
respondents indicated that they had reached out to a social media company to request information 
to use as evidence.5 
There has been increased attention—particularly following high-profile incidents such as the 
January 6, 2021, attack on the U.S. Capitol6—on how law enforcement might access and use 
certain information shared on social media platforms to help prevent and investigate criminal 
activity. This report provides an overview of how law enforcement may leverage social media to 
communicate with the public and to aid in gathering information and evidence as part of its 
investigative duties. It also discusses information sharing between social media companies and 
law enforcement and raises issues that policymakers may consider as they examine the broader 
issue of how law enforcement may use social media.7 
                                                 
1 For purposes of this report, social media is conceptualized as an internet-based platform that allows users to create 
individual and group profiles, generate content, and connect with other individuals and groups. These platforms include 
Facebook, YouTube, Instagram, Twitter, Pinterest, LinkedIn, Snapchat, WhatsApp, TikTok, Reddit, Nextdoor, and 
Parler among others. For more information on conceptualizing social media, see Jonathan Obar and Steve Wildman,

Policy, vol. 39, no. 9 (2015), pp. 745-750.

adults report having ever used) and Facebook (69%). Pew began its survey on this topic in 2005.

Law Enforcement and Technology: Using Social Media 
 
Social Media as a Law Enforcement Communication 
Tool 
Social media is one of many tools law enforcement can use to connect with the community. Law 
enforcement agencies, even without the use of social media, engage with the public to share and 
request information via newspaper, radio, television, and other media; push out bulletins on 
wanted persons; and establish tip lines to crowdsource potential investigative leads. However, 
social media provides degrees of speed and reach unmatched by many other forms of 
communication law enforcement uses to connect with the community.  
Officials and researchers have highlighted social media as a tool that law enforcement agencies 
can use to improve public relations and enhance community policing.8 For instance, the 
President’s Task Force on 21st Century Policing—a Department of Justice (DOJ) task force 
established to identify best practices and offer recommendations on how law enforcement 
agencies can both promote crime reduction and build public trust—specifically cited technology 
and social media as tools that law enforcement agencies can leverage to build community 
engagement and trust.9 The task force, in its 2015 report, noted that information shared on social 
media must be current and accurate so as not to harm trust and legitimacy. 
Many observers have pointed to the Boston Police Department’s use of Twitter during its 
evolving investigation of the Boston Marathon bombing in April 2013 as a social media use 
success story; reportedly, the Boston Police  
used  Twitter  to  keep  the  public  informed  about  the  status  of  the  investigation,  to  calm 
nerves and request assistance, to correct mistaken information reported by the press, and 
to  ask  for  public  restraint  in  the  tweeting  of  information  from  police  scanners.  This 
demonstrated  the  level  of  trust  and  interaction  that  a  department  and  a  community  can 
attain online.10 
Federal law enforcement agencies have turned to a variety of social media platforms, including 
Facebook, Instagram, Twitter, YouTube, LinkedIn, and others to share information.11 Some 
departments and agencies have designed policies specifically governing the use of social media to 
communicate with the public.12 
                                                 
8 For more information on community policing, see CRS Report R43904, Public Trust and Law Enforcement—A 
Discussion for Policymakers. There are different conceptualizations of community policing, but there are common 
elements of what many argue may constitute it. These include emphasizing partnerships, promoting citizen input, 
focusing on prevention and problem solving, rethinking officer assignments and organizational structures, fostering 
positive interactions, and sharing information.

Law Enforcement and Technology: Using Social Media 
 
Social Media and Investigations 
Just as social media is one of many communication platforms used by law enforcement, it is also 
one tool among many others in agencies’ investigative toolkits. There are a variety of means to 
help establish investigative leads and assemble evidence on potential suspects—including 
gathering information from social media sites. There are no federal laws that specifically govern 
law enforcement agencies’ use of information obtained from social media sites, but their ability to 
obtain or use certain information may be influenced by social media companies’ policies as well 
as law enforcement agencies’ own social media policies and the rules of criminal procedure.13 
The landscape of content available on social media platforms is broad, with users creating and 
sharing text, photos, and videos. Some platforms also have internal messaging services where 
users can communicate directly with other users of the platform.14 Access to this social media 
content is influenced by factors including social media platform policies and user controls. Some 
content is available to a broad audience without restriction; other content contains access 
boundaries. Individuals generally have some control over the intended audience with whom they 
share content. Facebook users, for instance, can elect to share content publicly, with only 
Facebook contacts/friends (or some subset of friends), with Facebook friends and their friends, 
with a specific Facebook group, or may post information privately that no one else sees. And, 
depending on settings, consumers of social media content may be able to, in turn, share or re-
share a friend’s/contact’s content, thus potentially expanding the audience of this content beyond 
what may have been initially intended by the individual who created or first shared it. 
Accessing Public Information 
When individuals post content on social media platforms without audience restrictions, anyone 
who visits the platforms—including law enforcement—can access this content. Law enforcement 
does not need to obtain court authorization to view content that has been published for any and all 
to see, like a sign in one’s yard.15 
In addition to content that one shares on social media, selected account-level information may 
also be available to a broad audience, including law enforcement, such as the information 
contained in a public profile. Depending on platform and user settings, this may include a host of 
demographic, geolocation, and other data, potentially including a list of other accounts with 
whom one is connected on a given social media platform. Law enforcement may use this 
information to learn more about an individual’s social network. 
                                                 
13 For instance, DOJ’s Justice Manual has guidelines on personal use of social media (see Section 1-9.000, 
https://www.justice.gov/jm/jm-1-9000-personal-use-of-social-media) and on evidence collection, including searches 
and seizures (see Section 1-13.000, https://www.justice.gov/jm/jm-9-13000-obtaining-evidence). Federal law 
enforcement agencies are also subject to the Federal Rules of Criminal Procedure. For more information, see CRS In 
Focus IF11557, Congress, the Judiciary, and Civil and Criminal Procedure.  
14 Access to these communications may be affected by social media policies, law enforcement rules for criminal 
procedure, and whether or not the communications are encrypted.  
15 In 1999, DOJ convened an Online Investigations Working Group with representatives from across DOJ as well as 
members from the Department of the Treasury, Department of Defense, and others. A copy of the working group’s 
November 1999 report, Online Investigative Principles for Federal Law Enforcement Agents, is available at 
https://info.publicintelligence.net/DoJ-OnlineInvestigations.pdf. It detailed a range of principles for online 
investigations. These principles may apply to investigations involving social media, though it is unclear to what extent 
federal law enforcement may rely on such principles today.

Law Enforcement and Technology: Using Social Media 
 
Although law enforcement may be legally and technically able to access public information on 
social media platforms, agencies may have internal policies governing this access. These internal 
policies may, for instance, place restrictions on the circumstances under which law enforcement 
can access social media for investigations as well as the authorization needed to do so.16  
Accessing Restricted or Private Information 
Based on platform policies or user choices, some information that individuals post on social 
media may contain restrictions regarding the breadth of the audience that may access that 
information. Some of these restrictions are established by platform controls and some may be 
established by user preferences. In the instances when law enforcement does not have public 
access to information, they may rely on a number of tools and techniques to gain access to it. 
For instance, law enforcement may rely on informants, or contacts of the persons about whom 
law enforcement is seeking information, to share social media information that they may have 
access to because of their status as a direct contact with the individual in question. Law 
enforcement may also operate undercover, posing as someone who may be more likely to gain 
access to an individual’s social media network in order to glean information.17 Some observers 
have suggested that law enforcement agencies should specifically address the use of online 
aliases in their social media policies to draw a distinction between the information they gather 
that is unrestricted and publicly available and that which they gather through the use of an alias.18  
Law enforcement may also require social media platforms to provide access to certain restricted 
information through a warrant, subpoena, or other court order. For instance, law enforcement may 
want to access private information from a particular individual’s account pursuant to an 
investigation and may need a warrant to do so. Similarly, as some social media posts or comments 
on public forums are made anonymously, law enforcement would generally need a warrant to try 
and obtain information from the platform on the identity of the anonymous poster. 
Preservation Request 
In some instances, law enforcement may present social media companies with a request to preserve certain 
content at a particular moment in time. This may be done to prevent content from being altered during the time it 
takes law enforcement to obtain the proper court authorization, such as a warrant, needed to obtain access to 
this content. Wire and electronic service providers as well as remote computing services, including social media 
platforms, are required to preserve content for 90 days at the request of law enforcement. This request may be 
extended once for an additional 90-day period.19 Fol owing the January 6, 2021, attack against the U.S. Capitol, 
                                                 
16 For instance, the Honolulu Police Department requires that officers obtain approval from the Chief of Police or a 
designee before using social media to conduct an investigation. See Honolulu Police Department, Policy, Organization, 
Management, and Administration, Policy Number 2.72: Social Media, May 21, 2019. Studies have recommended that 
law enforcement develop social media policies (see, for instance, Bureau of Justice Assistance with the Global Justice 
Information Sharing Initiative and Criminal Intelligence Coordinating Council, Developing a Policy on the Use of 
Social Media in Intelligence and Investigative Activities: Guidance and Recommendations, February 2013). It is 
unclear how many agencies have these policies or whether the policies may be publicly available. The Brennan Center 
for Justice has collected some publicly available social media policies and collated them online at 
https://www.brennancenter.org/our-work/research-reports/directory-police-department-social-media-policies. 
17 For instance, DOJ has guidelines for FBI undercover operations. These guidelines reference undercover operations 
online, but they do not have specific guidance on operations involving social media. See Department of Justice, The 
Attorney General’s Guidelines on Federal Bureau of Investigation Undercover Operations, May 30, 2002.

Media and Tactical Considerations for Law Enforcement, July 2013.

there was concern that participants in the attack and others may attempt to edit or remove content that they had 
posted, shared, or otherwise engaged with leading up to and fol owing the attack. As such, reporting indicates, 
federal investigators requested that companies such as Facebook, Twitter, and others preserve this content that 
could help in their investigations.20 
Platform Policies on Information Sharing with Law Enforcement 
Pursuant to the Stored Communications Act (Title II of P.L. 99-508), social media platforms may 
disclose information about users and their communications on the platform to law enforcement 
under certain circumstances. For instance, platforms may disclose certain information to law 
enforcement with a warrant or other valid court order. Platforms may also share information with 
law enforcement if they, in good faith, believe that there is an emergency involving a danger of 
death or serious injury.21 Social media platforms also have a lawful duty to report apparent or 
imminent violations of federal law pertaining to child sexual exploitation and child sexual abuse 
material.22  
Sharing Information on Child Sexual Abuse Material 
Violations of federal law with respect to child sexual exploitation and child sexual abuse material (CSAM) are the 
one area of malicious behavior on which electronic service providers—including social media platforms—must 
report if they have knowledge of its occurrence. The duty to report applies in instances of apparent or imminent 
violations of 18 U.S.C. §§2251, 2251A, 2252, 2252A, 2252B, or 2260 that involve child pornography, or what is 
commonly referred to as CSAM. Specifically, providers must report to the CyberTipline, which is operated by the 
National Center for Missing and Exploited Children (NCMEC).23 NCMEC makes these reports available to law 
enforcement investigating crimes relating to child sexual exploitation. 
The duty to report apparent or imminent child sexual exploitation does not also place a duty on providers to 
actively search for this content. Rather, the duty to report only applies to content that a provider becomes aware 
of. Nonetheless, some social media platforms such as Facebook have started to take steps toward proactively 
detecting this content in their systems.24 
Policymakers have debated whether this model, of requiring electronic service providers to report apparent or 
imminent violations related to child sexual exploitation, can or should be replicated for other forms of malicious 
behavior occurring online, with a specific focus on social media platforms. 
In addition to what is allowable or required by law, social media platforms establish internal 
policies, which may vary from platform to platform and may change over time, regarding 
information sharing with law enforcement.25 They may voluntarily share information with law 
enforcement that is not protected by, or in violation of, the privacy agreements they have 
established with their users. There is also the issue of whether social media companies are

disincentivized to proactively search for certain malicious content on their platforms if they are 
shielded from liability for content hosted on their platforms.26  
Even if social media companies want to share certain information with law enforcement, they 
may not be able to do so if the information is encrypted in such a way that the company cannot 
access it. For instance, WhatsApp Messenger implemented default end-to-end encryption on its 
platform in 2016. This form of strong encryption, what some have termed warrant proof 
encryption, prevents WhatsApp from accessing the content of communications, even if presented 
with a warrant, because it does not hold the key to unlock the encrypted communications.27 Meta, 
the parent company of WhatsApp, Facebook, and Instagram, announced that it would implement 
end-to-end encryption on Facebook’s and Instagram’s Messenger service; however, this 
encryption shift is reportedly delayed until at least 2023.28 
Intelligence Gathering via Social Media 
In addition to using social media to help communicate with the public and further investigations, 
law enforcement agencies also rely on it for intelligence gathering purposes. This is the use that 
arguably has generated the most questions from policymakers, analysts, and the public. There 
have been questions about the extent to which law enforcement is actually using social media for 
intelligence gathering, how they might store and use such information, whether this intelligence 
gathering can hinder First Amendment protected activities, whether social media monitoring may 
undermine privacy rights, and whether intelligence gathering disproportionally affects certain 
individuals or communities.29  
Social media companies have at times weighed in on the issue of social media monitoring by law 
enforcement. These companies provide access to their user data to developers that build tools to 
improve user experiences, conduct research, and monitor social media platforms, among other 
things.30 Following reports that some law enforcement agencies had been monitoring social media 
with developers’ tools built on platforms’ user data, some platforms changed their policies to 
expressly prohibit their user data from being used by law enforcement to monitor social media.31 
In addition, law enforcement agencies themselves have reportedly grappled with the extent to 
which they should gather and rely on information and intelligence gleaned from social media. For 
instance, some observers have suggested that agencies such as the Federal Bureau of 
Investigation (FBI) may be reluctant to regularly analyze public social media posts because that 
                                                 
26 Section 230 of the Communications Decency Act of 1996 (CDA) is generally seen as protecting social media sites 
from liability for hosting content. A discussion of the current debate surrounding Section 230 is outside the scope of 
this report; however, for more information, see CRS Report R45650, Free Speech and the Regulation of Social Media 
Content.

could be viewed as spying on the American public and could subsequently chill free speech.32 
Others, however, have noted that the benefits to national security and public safety from 
analyzing social media content outweigh the risks.33 The Attorney General’s Guidelines for 
Domestic FBI Operations (Guidelines) specifically note that online services and resources may be 
used in intelligence assessments that may help detect and interrupt criminal activities at their 
early stages. The Guidelines state that  
assessment  activities  may  proactively  involve  surfing  the  Internet  to  find  publicly 
accessible websites and services through which recruitment by terrorist organizations and 
promotion of terrorist crimes is openly taking place; through which child pornography is 
advertised and traded; through which efforts are made by sexual predators to lure children 
for purposes of sexual abuse; or through which fraudulent schemes are perpetrated against 
the public.34 
There are numerous instances of law enforcement relying on social media in support of 
intelligence assessments and investigations. For instance, following the May 2020 killing of 
George Floyd, there were numerous protests around the country, and FBI agents “monitored 
social media activity for imminent acts of violence.”35 The FBI has contracted with various social 
media monitoring companies to “obtain early alerts on ongoing national security and public 
safety-related events through lawfully collected/acquired social media data.”36 In addition, DHS 
is reportedly considering enhancing its existing intelligence efforts to examine information from 
social media to better understand potential security threats and identify likely targets.37 To do so, 
DHS may leverage the expertise of private companies to help analyze publicly available content 
posted on social media. This reevaluation of DHS’s capabilities in social media analysis comes 
on the heels of the January 6, 2021, U.S. Capitol attack; DHS intelligence reportedly did not 
detect and/or report the security threats that were discussed on social media.38 
In another example, the mayor of Chicago announced in August 2020 that the Chicago Police 
Department created a specialized social media task force to monitor online activity with the goal 
of preventing looting. The 20-person unit was tasked with collecting intelligence, including 
through the use of data analytics and searching social media pages and accounts that had been 
associated with organizing looting activity. The task force was also reportedly working with other 
law enforcement partners, including the FBI, to investigate looting incidents that had already 
occurred.39

Law Enforcement and Technology: Using Social Media 
 
Going Forward 
There is no specific federal legislative framework that governs law enforcement use of social 
media.40 Rather, there are laws and policies governing law enforcement investigations and 
intelligence gathering, broadly. Some observers, however, have questioned whether the nature of 
social media may place it in a qualitatively different category than law enforcement’s use of other 
investigative tools and have suggested that there should be enhanced boundaries with respect to 
law enforcement operations in these online spaces. For instance, some have suggested that law 
enforcement agencies should have written, publicly available policies on their use of social 
media; they should obtain local government approval before using these online spaces; they 
should obtain judicial approval for conducting undercover operations using social media; there 
should be restrictions on law enforcement contacting minors via social media; and law 
enforcement’s use of social media should be audited.41 Policymakers may consider these issues as 
they conduct oversight or debate legislation on law enforcement use of social media. 
Oversight of Law Enforcement Social Media Policies 
The President’s Task Force on 21st Century Policing, as well as various DOJ research 
partnerships,42 have recommended that law enforcement agencies develop policies governing the 
use of social media. For instance, the Bureau of Justice Assistance (BJA) sponsored a project in 
collaboration with the Global Justice Information Sharing Initiative43 that, in 2013, recommended 
“all law enforcement leadership support the development of a social media-related policy and 
associated procedures (or enhance existing policies) to guide personnel on accessing, viewing, 
collecting, storing, retaining, and disseminating (or using) information from social media sites, 
tools, and resources as a part of their authorized investigative and criminal intelligence 
activities.”44 Specifically, it recommended that a social media policy should accomplish the 
following: 
  note that use of social media will be in accordance with relevant laws, 
regulations, and agency policies; 
  define if and when use of social media sites/tools is permitted;  
                                                 
40 In addition, there is not yet a wide body of case law to help inform on how courts are viewing law enforcement’s use 
of social media.

43 The Global Advisory Committee (GAC) serves as a Federal Advisory Committee to the U.S. Attorney General. 
Through recommendations to the Bureau of Justice Assistance (BJA), the GAC supports standards-based electronic 
information exchanges that provide justice and public safety communities with timely, accurate, complete, and 
accessible information, appropriately shared in a secure and trusted environment. GAC recommendations support the 
mission of the U.S. Department of Justice, initiatives sponsored by BJA, and related activities sponsored by BJA’s 
Global Justice Information Sharing Initiative (Global).

Law Enforcement and Technology: Using Social Media 
 
  specify the authority needed to use information obtained from social media;  
  note that information acquired from social media will be evaluated to assess 
reliability and validity; 
  specify documentation, storage, and retention requirements surrounding 
information obtained from social media; 
  define any guidelines involving off-duty personnel using social media 
information in connection with official duties and when/how personal equipment 
may be used for an authorized law enforcement purpose; and 
  identify procedures for disseminating criminal intelligence and investigative 
products that contain information obtained from social media, including any 
parameters for disseminating personal information. 
Anecdotal reports of law enforcement officers being reprimanded for improper use of social 
media have highlighted the sensitive nature of law enforcement personnel using social media in 
their personal and professional capacities.45 Policymakers may seek to evaluate whether federal 
law enforcement agencies have social media policies in place as well as how the agencies conduct 
oversight of officers’ use of social media.  
Congress can legislate directly on federal law enforcement practices, and it can also influence 
state, local, and tribal policies and practices through the provision or withholding of grant 
funding. Programs such as the Edward Byrne Memorial Justice Assistance Grant (JAG) 
program46 and the Community Oriented Policing Services (COPS) program47 have been used to 
incentivize activities of state and local law enforcement and may be leveraged to influence the 
adoption of social media policies. The federal government can also affect state, local, and tribal 
policies through the transfer of knowledge and expertise. For instance, BJA and its partners have 
provided guidance and recommendations on developing a social media policy that law 
enforcement agencies may reference.48 
Data on Frequency of Social Media Use in Investigations and 
Intelligence Gathering 
Although there have been some surveys of law enforcement on how they use social media and for 
which purposes, data are lacking on the extent to which law enforcement agencies leverage public 
information on social media platforms as well as restricted information gleaned through lawful 
means such as warrants and subpoenas. Some observers report that law enforcement has 
increasingly turned to social media content to assist in their investigations, while others have 
suggested that some law enforcement agencies are shying away from analyzing public social 
media posts because it may be viewed as spying on the public.49

Law Enforcement and Technology: Using Social Media 
 
Congress may consider tasking oversight entities such as the Government Accountability Office 
or department-level Inspectors General with reporting on issues such as whether law enforcement 
agencies have established clear parameters on the use of social media for investigations and 
intelligence gathering, whether or how agencies note the use of social media in investigative case 
files, and whether or how agencies tabulate metrics on their use of social media or other related 
tools. Congress may also request such information from law enforcement agencies directly 
through letters, hearings, and other oversight. A greater understanding of the purposes for and 
extent to which law enforcement relies on social media in its investigations and intelligence 
gathering may provide a stronger foundation for policy discussions going forward.
