The Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) is a program of the United States government used to collect and share reports of suspicious activity by people in the United States.[1][2] The Nationwide SAR Initiative (NSI) builds on what law enforcement and other agencies have been doing for years — gathering information regarding behaviors and incidents associated with criminal activity — but without the customary restrictions on collecting data on individuals in the absence of reasonable suspicion or probable cause. The program has established a standardized process whereby SARs can be shared among agencies to help detect and prevent terrorism-related criminal activity. This process is in direct response to the mandate to establish a "unified process for reporting, tracking, and accessing [SARs]" in a manner that rigorously protects the privacy and civil liberties of Americans, as called for in the 2007 National Strategy for Information Sharing (NSIS),[3] which in turn was authorized by the Intelligence Reform and Terrorism Prevention Act of 2004.[4] Reports of suspicious behavior noticed by local law enforcement or by private citizens are forwarded to state and major urban area fusion centers as well as DHS and the FBI for analysis. Sometimes this information is combined with other information to evaluate the suspicious activity in greater context. The program is primarily under the direction of the US Government & U.S Department of Justice.[2][5]
