About the Campaign

"If You See Something, Say Something®" is a national campaign that raises public awareness of the indicators of terrorism and terrorism-related crime, as well as the importance of reporting suspicious activity to state and local law enforcement.

Campaign History

The "If You See Something, Say Something®" campaign was originally implemented and trademarked by the New York Metropolitan Transportation Authority and is licensed to the U.S. Department of Homeland Security (DHS) for the purpose of creating a nationwide campaign.

In July 2010, DHS launched the campaign in conjunction with the U.S. Department of Justice's Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI), with the goal of training state and local law enforcement to recognize behaviors and indicators of terrorism and terrorism-related crime. The NSI standardizes how these observations are documented and analyzed. It ensures that reports are shared with the Federal Bureau of Investigation-led Joint Terrorism Task Forces for investigation and with state Fusion Centers for analysis. Only those reports documenting behavior that is reasonably indicative of terrorist activity will be shared with federal and state, local, tribal and territorial (SLTT) partners.
