Ten years after the school massacre at Columbine High School in Colorado, school shootings are a new and alarming epidemic. While sociologists have attributed the trigger of violence to peer pressure, such as bullying and social isolation, prominent psychologist Peter Langman, argues here that psychological causes are responsible. Drawing on 20 years of clinical experience, Langman offers surprising reasons for why some teens become violent. Langman divides shooters into three categories, and he discusses the role of personality, trauma, and psychosis among school shooters.
