Excellent. Well-presented. That should be required viewing by EVERYONE not just "gun people". I like how he points out that the Hollywood stereotype of a gunfight is b-s. Except then the bad guys might not be so afraid of our defensive pistols when they learn they aren't as deadly as most people think. HHhmmmmm.
Two things I take away from it that sound counter-intuitive and require further study.
1) If hollowpoints don't penetrate enough to get to vital organs, then are we not better off with solids, FMJ's or solid leads? I carry Hydra-Shocks and Silvertips depending on caliber.
2) If a crouched stance will lead to a bullet going into your chest, traveling DOWNWARD through your body and into your abdomen, then would you be better off to stand up straight and get a shorter, less damaging, possibly through-and-through wound channel? The advantage certainly would be presenting less of a target, obviously.
