About the NSI

About NSI The findings in The 9/11 Commission Report and the Markle Foundation report1 clearly demonstrated the need for a nationwide capacity to share information that could detect, prevent, or deter a terrorist attack. The Intelligence Reform and Terrorism Prevention Act (IRTPA) of 2004 and the 2007 National Strategy for Information Sharing indicate both legislative and executive intent to establish locally controlled distributed information systems wherein potential terrorism-related information could be contributed by the 18,000 state, local, tribal, and territorial (SLTT) law enforcement agencies for analysis to determine whether there are emerging patterns or trends. Following this guidance, the Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) was developed.

The NSI is a partnership among federal, state, local, tribal, and territorial law enforcement that establishes a national capacity for gathering, documenting, processing, analyzing, and sharing SAR information—also referred to as the SAR process—in a manner that rigorously protects the privacy and civil liberties of Americans. The ISE-SAR Functional Standard v. 1.5.5 defines suspicious activity as “observed behavior reasonably indicative of pre-operational planning associated with terrorism or other criminal activity.” This definition was developed after critical input from several privacy, civil rights, and civil liberties advocacy groups, including the American Civil Liberties Union (ACLU). The SAR process is critical to sharing information about suspicious activity with a potential nexus to terrorism, which can help prevent terrorist attacks and other related criminal activity from occurring. In developing the standards and processes, the NSI leveraged the guidance and expertise provided by the Global Justice Information Sharing Initiative (Global), which serves as a Federal Advisory Committee and advises the U.S. Attorney General on justice information sharing and integration initiatives. This includes leveraging the National Information Exchange Model (NIEM), which allows the interoperability and seamless exchange of information.

The NSI is a collaborative effort among SLTT and federal agencies, led by the U.S. Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI), in coordination with the Program Manager for the Information Sharing Environment (PM-ISE), Global, and the Criminal Intelligence Coordinating Council (CICC). Support of the Nationwide SAR Initiative (NSI) efforts has been publicly stated by major law enforcement associations, including the International Association of Chiefs of Police (IACP), the Major Cities Chiefs Association (MCCA), the Major County Sheriffs’ Association (MCSA), the National Sheriffs’ Association (NSA), and the Association of State Criminal Investigative Agencies (ASCIA).
