The purpose of licensed carry is self-defense. Such a license does not designate the holder as a reserve policeman. Therefore, if the concealed carrier intervenes in a mass shooting situation, other than to directly protect himself, he oversteps the bounds of his license and leaves himself open to adverse legal
consequences.
No. Most if not all states include defense of others under the laws governing self defense.
So it begs the question, should lawfully armed citizens intervene, or not.
There are definite risks and those risks often come from a critical lack of understanding of the situation. For example...
1985 Springfield Mall, PA, Sylvia Seegrist killed 3, injured 7, was stopped by unarmed mall store employee who thought her gun wasn't real. This hero got very lucky despite his ignorance.
2005 Brenden McKown at Tacoma Mall - engaged a shooter verbally and did not have his gun drawn, fearing being confused for the shooter by the cops and claiming he didn't have a shot on the shooter. McKown was shot multiple times and was crippled as a result. McKown intervened stupidly, but with good intentions.
2005 Mark Wilson engaged an active shooter down on the square in Tyler, Texas, apparently seeing the shooting start from his apartment window overlooking the square. The firearms instructor strangely opted to respond with his pistol where upon he engaged the active shooter who was wearing body armor and who summarily killed Wilson. Wilson was credited for wounding the shooter and changing the course of events, but was killed. He had actually shot the shooter multiple times, but the vest protected the shooter from all but one shot. Wilson apparently did not realize the shooter was wearing a vest.
2011 - Giffords shooting, Joe Zamudio responded to the shooting and nearly shot the wrong person as he admitted to the press. Zamudio arrived AFTER the shooter had been disarmed and the person he claims to have almost shot was securing the weapon.
2014 - LV Walmart, David Wilcox apparently entered the situation not realizing how many opponents he was engaging, and was killed as result. Apparently, he drew, but never fired a shot.
