You just never know, that’s for sure! ;-)
ALL OF THESE GUYS laughed when I, outraged at the time, told them about the "experts" on this forum who assured fellow FReepers that that shooter in Aurora, Colorado, couldn't have been stopped because of his body armor. Every one of them said that the impact from a .45, and for sure the rapid succession of impacts from a .45, on that body armor (no "head shot" involved) would 99 percent likely unbalance and knock down the shooter long enough to overpower him. They don't "live in TV land."
