Just watched the full video. What a bunch a horse puckey!
In my opinion the 5.7 penetrated specifically because of its smaller sizer and pointed projo. Very similar to why a vest will not stop a 22 or for that matter a knife.
But the most disturbing part of the video, to me, is when he states "this round serves no purpose for the public"
If some individual has a bad day (as he put it) and goes nuts on an officer, there are no guarantees the officer will make it out because of the vest alone, nor the cartridge used. Bottom line, bad people do bad things. And does anyone know of statistics anywhere that show when the last shooting rampage or flip out was done by a legal CCW owner?
Here in Michigan, this was the argument that the antis used against our new CCW law, that someone would go nuts and start shooting people. In the couple of years it has been in effect, to my knowledge, this has never happened.
