    U.S. Secret Service National Threat Assessment Center Report: Mass Attacks in Public Spaces 2018

    This report is NTAC’s second analysis of mass attacks that were carried out in public spaces, and it builds upon Mass Attacks in Public Spaces – 2017 (MAPS-2017). In MAPS-2017, NTAC found that attackers from that year were most frequently motivated by grievances related to their workplace or a domestic issue.  All of the attackers had recently experienced at least one significant stressor, and most had experienced financial instability. Over three-quarters of the attackers had made threatening or concerning communications, and a similar number had elicited concern from others. Further, most had histories of criminal charges, mental health symptoms, and/or illicit substance use or abuse.

ASIS are most likely to happen at the high school level or higher (37 out of 52). The average deaths from ASIS was 7.4; however, this includes the 2007 Virginia Tech shooting and the 2012 Sandy Hook Elementary School shooting, where 32 and 26 people died, respectively.

    FBI Study: Pre-Attack Behaviors of Active Shooters in the U.S. 2000-2013

    In 2017 there were 30 separate active shootings in the United States, the largest number ever recorded by the FBI during a one-year period.1 With so many attacks occurring, it can become easy to believe that nothing can stop an active shooter determined to commit violence. “The offender just snapped” and “There’s no way that anyone could have seen this coming” are common reactions that can fuel a collective sense of a “new normal,” one punctuated by a sense of hopelessness and helplessness. Faced with so many tragedies, society routinely wrestles with a fundamental question: can anything be done to prevent attacks on our loved ones, our children, our schools, our churches, concerts, and communities?
