Abstract

The Nationwide Suspicious Activity Reporting Initiative (NSI) established a national infrastructure for sharing information related to terrorist activity. Fusion centers facilitate the receipt, investigation, documentation, and sharing of suspicious activity reports, or SARs. Eighty fusion centers currently operate across the United States, but research into how these centers process SARs is limited. Using closed-source data on SARs from two fusion centers, this brief describes the characteristics of SARs in terms of intake, triage, and outcome.
