Stopping Mass Shootings Before They Happen

Mother Jones national affairs editor Mark Follman has studied mass shootings in America for much of the past decade. He says a growing number of mental health experts, educators and law enforcement leaders are engaged in the emerging field of behavioral threat assessment. They study the psychology and behavior of past mass shooters, interviewing many in prison. They then train local personnel to look for those patterns at schools or workplaces, and intervene to get troubled people help before they turn to violence. The approach raises privacy questions, but its advocates believe it's already been effective in preventing tragedies. Follman's new book is Trigger Points: Inside the Mission to Stop Mass Shootings in America.
