I will be the first to admit that, not being an attorney, I am not 100% sure what the letter of the law says.
But, to be perfectly honest, even if I lived in a state that gave me more broad rights of self defense, my response would be the same. I would not kill someone over a TV or personal property.
Conversely, I really don't care what the law says if someone is trying to kill me or my loved ones. I am going to return fire if capable.
There are some things that are worth spending the rest of your life in prison for. Regardless of what the law says. If someone seriously hurt my wife or kids, or tried to, I really wouldn't care what the law said.
I'm not claiming to be Billy Bad Ass or trying to be an internet tough guy, but the laws of God supersede the laws of man. I believe that when you take a wife and have a family you should be willing to do whatever is necessary to keep them safe. Hopefully, you can do this without breaking the law.
