Did you read my post, look at the picture, and look at the price?
It’s not armor. Armor is not wide open in the center of the chest. Armor does not cost $108.
It’s an ammo vest. And I am just guessing that is what he wore. The typical college student likely doesn’t have real armor.
A .45 can’t knock a person over just by the impact. But you are right that an armored person will be stunned and may be put out of commission by a few good hits from a .45.
For the record, I honestly didn't know if a gun would have done any good in the circumstances. They all pointed out that if one or two guys in that theater had been carrying .45s (instead of .38s), and it is understood that responsible CCers carry at least one extra clip, the impact of hits would certainly put the wacko at an extreme disadvantage, staggering him and probably knocking him down. The smaller the wacko, the likelier the dive.
They also said that .38s probably couldn't do that, and a lot of these guys carry .38s.
But yes, I did understand that the vest you posted was not the "bullet proof vest" that TV land (ha ha!!) has it cracked up to be. :^)
