LOL...there is a concealed handgun instructor here that, humorously, teaches that after your attacker goes down, be sure to give him chest compressions until the cops arrive.
1) The attacker exsanguinates before the cops arrive, and
2) Cops will testify upon pulling up that the shooter was giving first aid, giving credence to the trained CCW shooter that he/she didn't want to kill the attacker, but simply shot the attacker until the attack stopped.
I train them to maintain security, reload, and then dial 911 and don't touch the damn blood. If it was a good shoot, you don't have to do much after "BANG" other than tell the cops you were in fear for your life, and you want any statements made in your lawyers office.
Absolute best advice and I remind my loved ones about it periodically.
That my FReeper friend is the best advice any CCW permit holder should have been given.
Just put the gun down, step away from the hopefully dead perp, keep your hands visible , tell them you were afraid for your life and then STFU. NOTHING at all, just that you want to talk to a lawyer. NOTHING ever...
Don't describe the scene, the scenario, who did what, what color the sky was, what you THINK he was doing, NOTHING. Just shut your pie hole and get your lawyer.
Saving your life may cost you some money, but it's better than going to court for some DA or LEO that wants to make a name for themselves.
