The U.S. Department of Homeland Security, the FBI, and the National Counterterrorism Center have released a product as part of their First Responder’s Toolbox series describing how terrorist organizations use disinformation to attempt to influence Western audiences. It includes examples of official media releases by these groups, including an image depicting an Islamic State supporter with a sniper rifle atop a building in downtown Denver, Colorado that appears to have been intended to inspire followers and create a sense of fear among the public. The product provides series of steps for how one should approach these messages when they are encountered, which can help inform determinations about the likelihood of violence actually being planned and committed.
