ALTERED STATES: Here’s What A Criminology Professor Learned By Studying Every Mass Shooting Since 1966 | RIELPOLITIK
First, the vast majority of mass shooters in our study experienced early childhood trauma and exposure to violence at a young age. The nature of their exposure included parental suicide, physical or sexual abuse, neglect, domestic violence, and/or severe bullying. The trauma was often a precursor to mental health concerns, including depression, anxiety, thought disorders or suicidality.
Second, practically every mass shooter we studied had reached an identifiable crisis point in the weeks or months leading up to the shooting. They often had become angry and despondent because of a specific grievance. For workplace shooters, a change in job status was frequently the trigger. For shooters in other contexts, relationship rejection or loss often played a role. Such crises were, in many cases, communicated to others through a marked change in behavior, an expression of suicidal thoughts or plans, or specific threats of violence.
Third, most of the shooters had studied the actions of other shooters and sought validation for their motives. People in crisis have always existed. But in the age of 24-hour rolling news and social media, there are scripts to follow that promise notoriety in death. Societal fear and fascination with mass shootings partly drives the motivation to commit them. Hence, as we have seen in the last week, mass shootings tend to come in clusters. They are socially contagious. Perpetrators study other perpetrators and model their acts after previous shootings. Many are radicalized online in their search for validation from others that their will to murder is justified.
