The Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) is a joint collaborative effort by the U.S. Department of Homeland Security, the Federal Bureau of Investigation, and state, local, tribal, and territorial law enforcement partners. This initiative provides law enforcement with another tool to help prevent terrorism and other related criminal activity by establishing a national capacity for gathering, documenting, processing, analyzing, and sharing SAR information.
