The FBI just published A Study of Pre-attack Behaviors of Active Shooters in the United States Between 2000 and 2013. FBI behaviorists believe that there is cause for hope to prevent active shooter attacks because there is something that can be done. In the weeks and months before an attack, many active shooters engage in behaviors that may signal impending violence. While some of these behaviors are intentionally concealed, others are observable and — if recognized and reported — may lead to a disruption prior to an attack. Train your staff and others to be on the lookout for signals, report them and be prepared to convey concerns to law enforcement agencies. You can read their key findings below and a wide variety of active shooter background and planning resources at: www.jcrcny.org/activeshooter.
