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

July 10, 2019

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.
