Here in GA we have a law called the "no retreat law" which means that you have a right to protect your property and dwelling in the event a tresspasser or burglar attempts to harm you or your property. I could not legally shoot him in the back if he was trying to run, but I could shoot him anywhere on my property if he attacked me or I feared for my life. A warning shot is not a problem either as I was on my property and we are out in the country. Hell, I have a firing range in my backyard that I sight a rifle in on.
I did not want to kill the man, but I was not going to let him harm me or my family. When I approached him as he was trying to get in the house, my first question to him was "do you know what this is?". I was referring to the 9mm I had in my hand at chest level to ensure he knew I meant business. I think the only reason he did not run was not because of the gun, but because of the 80 pound doberman standing in the doorway watching him. I made sure he knew that I was military and could shoot, made sure he was aware of the dogs, made sure he knew I knew what the gun laws were and then that I meant it by firing a warning shot. He did have a folding knife on him, but I did not know that until the sheriff searched him. I am very grateful for my training as I kept about 10 feet from him and maintained sight and control 100% of the time. If he or his buddies decide to come back, it may not go as well, but I will be ready for them then too. Everything in the garage is insured, so I can deal with that. If they come armed, then there will be shots fired and I can only hope for the best and protect my way of life and family.
I don't think anyone would miss this POS other than his mother.
