It is for protection, not killing. And it depends on where you shoot them. Shoot them in the legs and you take out their ability to run, leaving you safe and them in a condition easy enough for the cops to apprehend. My intentions are not to kill. If I wanted to do that, I would simply run them over with my truck. That is why it stays in my truck. If I am being attacked in my truck they are close enough I could do damage to them. If they are running away - what is the point in shooting. If they are far enough away that the gun will not hurt them, then I am far enough away to escape.
It is self-defense, not kill and destroy.
