It seems like I've read or heard alot of stories where shooting wasnt justified because the attacker was shot in the back. The question I have is if I am shooting at someone that is in my house and armed, it seems thats generally ok if they're facing me, but what if they turn to run? How do I know they're not just going to regroup, or run into another room for cover? I have a fairly large house, lots of places to run to and hide. Letting them regroup would be a fatal mistake. I know this varies from state to state, but what are your general thoughts about this?
