As the ways in which individuals interact continue to evolve, social media has had an increasing

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.
2 Pew Research Center, Social Media Fact Sheet, April 7, 2021. The most widely used platforms are YouTube (81% of
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.

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.

Brookings, July 9, 2020.

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

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.
