The number one thing to remember about shooting a criminal in your home, don't shoot him in the back. Number two rule, make sure you kill the bastard. Dead men tell no lies. No cop will officially tell you these two rules but you can bet all his family and friends are aware of it.
Is my memory failing me? ;^)
Another thing that a cop won't tell you, at least not officially: After you've emptied the magazine, empty your bladder (if you haven't done so already). Make sure that this gets noted in the police report.
The perp's lawyer: "Were you really scared for your life?"
You: "I was so scared..."

IIRC, the new Texas laws let you shoot him in the back. This should be the Law of the Land across the USA.
