1) Only shoot as an absolute last resort after all else fails. 2) Never use reloads for self defense. If the criminal court doesn't hang you, the civil court will. 3) Don't drag the body inside the house. Tampering will get you big jail time and the jury will tend to question your motive in 'defending' yourself. 4) If the perp surrenders or is incapacitated cover him but DON'T SHOOT HIM AGAIN UNLESS YOU HAVE DO, like he resumes the attack. 5) Call the Police ASAP 6) If it can be done safely render First Aid 7) If an ambulance arrives backoff and let them do their deal 8) Generally co-operate with the Police. A) When ordered to, put the gun down B) Rasie your hands and assume a surrender posture, an officer will tell what you need to do, follow his directions C) If read your rights ask for a Lawyer then shut your mouth, you have been arrested. D) Tell the first Officer on the sence exactly what you did and why E) Don't sign crap F) Ask for a blood test unless you are drunk or stoned G) Yes, do let them fingerprint you and take your picture 9) Don't talk to the press 10) Don't tell your friends all about how you did the deed 11) Don't try to make yourself into a Hero, if you are people will say so, if not......oh,well 12) Do seek counseling, from a Preacher, Psychiatrist or other Professional 13) Don't worry about the dreams, they will pass, if not go back to #12 I may think of some other stuff later but this is a good start. BTW, I've been a Cop of some kind for 31+ years. I'm not telling you this stuff to get you off from murdering someone, most of these things are what I've done myself. Only shoot if you have too.
