defacto: If she had hit the Kevlar it still could have killed him. The injuries can be pretty nasty and life threatening depending on the weapon. Broken bones, concussions, internal bleeding and organ injury... this was sheer stupid in action.
True; but, presuming he had it on fairly properly, how could she have missed the bpv & still hit him in the chest? I have one, am wearing it right now at the library in fact, & it covers from the sternum down to the navel, does the chest comprise any area outside of this? perhaps they mean the esophagus adams app or lower neck is all I can think of.
Could hit a glancing blow to the outer ribs I suppose, but doesn't seem like that would be fatal, just, er, painful. Cracked ribs, ow.
I nominate the victim for a posthumous Darwin award.
Notes: 4 levels of bullet vests (iirc), II (lowest), IIA, III, IV (only one which will stop some ~2800 fps rifle bullets). There's a 'rifle plate' about 5" x 7", hard ceramic plate or something like that, which fits in a pocket over the heart, will stop rifle bullets - much better than a bible in your shirt pocket.
2 BPV's deteriorate in heat, like a hot car, or rather the Kevlar does. Kevlar will deteriorate after 10 years or so, mine is like 20 yrs police surplus, got it for ~$150 ten years back maybe. It'll still work pretty well tho. Don't work very well against daggers, just blunt the thrust.
3 Been arguing with gunnutted crowd for over a decade & only met two gun owners who had bullet vests & one didn't wear it any more. For all their worry & angst about being surprised by hell bent thugs & shot, they tend not to wear the simplest & best deterrent to getting fatally shot, no, no, they think all they need is their gun - shows how disingenuous their argument is, they mainly want it to feel big.
