The problem with this is that most of America’s knowledge about guns comes from watching movies. Where if I shoot somebody with a .45, they fly backwards out the window, do a flip, roll fifty feet, and burst into flames.
To put this in perspective, when you shoot somebody in self defense, the goal isn’t necessarily to kill them, it is to stop them. You want the bad guy to stop doing whatever it is they are doing that caused you go pull a gun in the first place. Live or die is really irrelevant. You want them to leave you alone. Sadly, the best way to make somebody leave you alone is to shoot them in their vital organs, and that often results in the bad guy’s death. But that’s his problem, not yours.
