Preventing School Shootings
In 2023 (until the end of September), at least 54 shootings took place in schools and universities, impacting surrounding communities. Deaths by school shootings account for a small percentage of gun deaths among youth to date, but the numbers have been increasing since 2017. Such events require more accurate risk assessment training to prevent future incidents. This workshop will identify and describe three psychological types of school shooters: traumatized, psychotic, and psychopathic. Each will be illustrated through a case history. The workshop will then present an overview of threat assessment, discussing the concepts of “leakage,” “attack-related behavior,” and “evidence of imminence,” along with examples of warning signs from actual school shootings.
(Case material will include personal writings and drawings from perpetrators, which contain explicit content some might find disturbing.)
NCSPP is aware that historically psychoanalysis has either excluded or pathologized groups outside of the dominant population in terms of age, race, ethnicity, nationality, language, gender, religion, sexual orientation, socioeconomic status, disability, and size. As an organization, we are committed to bringing awareness to matters of anti-oppression, inequity, inequality, diversity, and inclusion as they pertain to our educational offerings, our theoretical orientation, our community, and the broader world we all inhabit.
Presenters Response:
Violence and psychopathy have been perceived historically as occurring primarily in specific racial, ethnic, geographical, and socioeconomic domains. This training will show that psychopathy and school shootings are not centered in these stereotypes and will review traits of school shooters across populations.
At the end of this course participants will be able to:
- Describe the three psychological types of school shooters.
- Explain the terms “leakage,” “attack-related behavior,” and “evidence of imminence.”
- Describe at least 3 warning signs of potential rampage attacks.

Peter Langman, Ph.D., is a known expert in the psychology of school shooters. His trainings identify warning signs of potential perpetrators of violence before it occurs and how school leadership can effectively utilize threat assessment across their communities. This includes analyzing homework assignments, understanding motivations and justifications for violence, and exploring pathways to violence.
