If You See Something, Say Something

Overview
In July 2010, DHS launched the “If You See Something, Say SomethingTM” campaign to raise public awareness of indicators of terrorism and terrorism-related crime and to emphasize the importance of reporting suspicious activity to the proper law enforcement authorities. The “If You See Something, Say Something™” campaign was originally implemented by New York City's Metropolitan Transportation Authority and is now licensed to DHS for a nationwide campaign.
