Will proponents of teachers with guns give an iron-clad guarante

Avalon - Will proponents of teachers with guns give an iron-clad guarantee that none of the following will ever happen: One or more students overpower an armed teacher, take the gun, and kill other students and teachers. A teacher under unrecognized emotional stress "loses it" and commits mayhem with his gun. An assailant with an assault rifle, believing he will encounter an armed teacher, targets teachers first and then turns his attention to students. Fact: a deranged individual with an assault rifle, the intent to kill, and the element of surprise, will not be deterred by pistol-packing teachers.
