Backers of laws that let pretty much all law-abiding people carry concealed guns in public places often argue that these laws will sometimes enable people to stop mass shootings. Opponents sometimes ask: If that’s so, what examples can one give of civilians armed with guns stopping such shootings? Sometimes, I hear people asking if even one such example can be found, or saying that they haven’t heard of even one such example. This prompted me to post in late 2015 about 10 such incidents that I had found in roughly the preceding 20 years.
Thanks to a recent FBI report, we have more data on 2016-17. The FBI found 50 shootings throughout the U.S. that it labeled “active shooter incidents”—”one or more individuals actively engaged in killing or attempting to kill people in a populated area.” Of those, four involved situations where the FBI believes that “citizens possessing valid firearms permits successfully stopped the shooter.” (Four others involved “unarmed citizens [who] confronted or persuaded the shooter to end the shooting.”)
On September 28, 2016, at 1:45 p.m., Jesse Dewitt Osborne, 14, armed with a handgun, allegedly began shooting at the Townville Elementary School playground in Townville, South Carolina. Prior to the shooting, the shooter, a former student, killed his father at their home. Two people were killed, including one student; three were wounded, one teacher and two students. A volunteer firefighter, who possessed a valid firearms permit, restrained the shooter until law enforcement officers arrived and apprehended him. [UPDATE: A commenter points out that the firefighter apparently restrained the shooter after the shooter’s only gun had already jammed, though the firefighter apparently hadn’t know when he went looking for the shooter; the FBI report did not note this.]
On September 24, 2017, at 11:15 a.m., Emanuel Kidega Samson, 25, armed with two handguns, allegedly began shooting in the parking lot of the Burnette Chapel Church of Christ in Antioch, Tennessee. After killing one person, the shooter entered the church and shot six people. A citizen who attempted to subdue the shooter was pistol-whipped. During the altercation, the shooter accidently shot himself. While the shooter was preoccupied, the citizen, who possessed a valid firearms permit, retrieved a handgun from his car and held the shooter at gunpoint until law enforcement arrived. One person was killed; seven were wounded. The shooter was apprehended by law enforcement.
