“The FBI looked at 160 active-shooter situations from 2000 to 2013 and found only one case where an armed civilian intervened to stop an attack that was underway. (And that civilian was a US Marine.) In 21 cases, an unarmed civilian interrupted the attack and restrained the gunman. In other words, unarmed civilians were far more likely than those with guns to stop an active shooting in progress.” – Samantha Michaels in New Research Confirms Guns on College Campuses Are Dangerous [via motherjones.com]
