not that I'd want to be in the situation, but I think in AZ you can legally kill someone in self defense if they are in your home. I'm not sure how I'd act in a high pressure situation. would I want to pump the gun trying to scare someone off, or take them out and have one less bad guy on the streets? I'm told that if you own a gun that the shooting ranges tell everyone to go for a head shot so they can't come back and try to sue you.
