This LSU NCBRT presentation provides participants with an overview of the fundamentals of Suspicious Activity Reports (SARs). The Information Sharing Environment (ISE) is the platform on which the National Terrorism Information Sharing and Suspicious Activity Reporting (SAR) initiatives are managed. A suspicious activity is an observed behavior reasonably indicative of preoperational planning related to terrorism or other criminal activity. It is critical for agencies to share collected information. SARs record suspicious activities that need further inquiry and follow-up.
