******** left the theater & returned not only with the weapons & ammo but also wearing body armor. Even if anyone else in the theater was armed and they managed to only hit the perp and not other theater-goers, it is doubtful if it would have done any good at all once you realize that they would have had to get a really lucky shot into a seam between the armor elements, have armor-piercing rounds, or a REALLY heavy caliber weapon. A bullet-resistant vest can stop a .357 Magnum round just inches away. How many people are going to be carrying around something more powerful than that?
