Presented by Peter Langman, PhD

The workshop will identify and describe three psychological types of school shooters. Each of these types will be presented through case histories of actual perpetrators. The workshop will also discuss the life circumstances of the perpetrators, who often endured multiple blows to their identities. The workshop will then address warning signs of impending violence. A distinction will be made between reactive emergency response procedures such as lockdown drills that are utilized after an armed intruder has entered a building or campus, and threat assessment as a proactive approach to identify a potential violent attacker before he shows up armed and ready to kill.


1.      Describe the three psychological types of school shooters.

2.      List three common domains of failures that shooters often experience.

3.      Explain the terms “threat assessment,” “attack-related behavior” and “leakage” and describe warnings signs of potential rampage attacks.
