What Next: The Mass Shooter Database

Why does someone become a mass shooter? Researchers are interviewing perpetrators and their victims—and those who narrowly averted committing a mass shooting—and discovering a common thread of psychological despair. Can their work be applied to the prevention of future violence?

Guest: Jillian Peterson, forensic psychologist, violence researcher, and author of The Violence Project.
