FBI Report Details Commonalities Among Active Shooters
A new FBI report on active shooters says that mass shooters don’t explode out of nowhere—they plan and prepare. Most have no diagnosable mental illness. And their attacks are almost always preceded by behaviors that stir apprehension in people close to them, possible warning signs that crop up over a lengthy period of time.
The study, coauthored by criminal justice professor James Silver of Worcester State University and Supervisory Special Agent Andre Simons and Dr. Sarah Craun of the FBI’s Behavioral Analysis Unit, examined 160 active shooter incidents between 2000 and 2013.
