General Discussion

CBS News analyzed a database compiled by The Violence Project. The nonprofit tracks mass shootings, which it defines as four or more people murdered in one event, not including the offender. It shows out of 195 mass shootings since 1966, 50 involved suspects who were veterans or people with military training.

To be clear, only a tiny fraction of people with military backgrounds become mass shooters. But military experience is something a disproportionate share of attackers have in common.
