I think we all agree that IF we have to shoot for our safety we are shooting to stop the threat and not to kill the person.
My wife is an EMT and she carries (when she's off duty). My question is, if you had the first aid training, would you provide care to the person that you shot?
I cannot agree with you on your first statement. I was always have been taught or trained to first give the perp every chance to leave your home and or area. Also you have no idea what what the perp is on, i.e., Angel Dust/PCP, LSD, Coke, Heroine, etc., and one needs to shoot to kill and to empty your firearm as he is there for one of two things to rob you, then let him have whatever he wants, or he is there to murder you and your family. There is a third possibility and that is a home invasion and you may be pistol whipped, females raped and beaten, children murdered. No matter why he is there the perp is uninvited and up to no good does not belong there. You wound this person the perp he will have an attorney and sue you, and if you kill him his family will sue you whether they liked him or not ,so you are screwed in any case. But I would rather be tried by 12 than carried by 6 and take my chances in a Civil Court.
The second part is, read my first part
If he's DEAD, he's STOPPED, isn't he?
If he's stopped and you "shoot to kill and to empty your firearm" you will have a long painful relationship with some lifer in prison. I have 19 rounds in a Glock, or 30 in my rifle, if he is stopped by multiple rounds to center mass and possibly a head shot if there is a failure to stop (not failure to kill) he's likely going to die, which really is a personal problem because he chose to force me to shoot him.
But if he's stopped, you really believe you should "empty your weapon?" I could have anywhere from 16 - 27 rounds left, THAT will be hard to justify in any court. Look at the pharmacist who shot the robber in the head with his first shot and chased BG # 2 out of the store. He returned to the scene, took out a second gun from a drawer, and shot BG 5 more times on the floor. Was he still a threat? The pharmacist obviously didn't view him as a threat anymore since he took the time to get a second gun and go off camera before firing. Oh BTW he was just convicted of MURDER.
The training I've received and given teaches multiple rounds center mass with a follow up to the head if necessary. Is this the most likely way to kill him? You bet'cha. It is also the FASTEST WAY TO STOP THE THREAT.
Just one witness with a camera phone or a lawyer finding your opinion that you "need to shoot to kill and empty the weapon" or even a slip of the tongue saying something similar, will guarantee a prison term and your family will have to deal with the civil suit.
Take it from someone who's BTDT, you don't want to kill the other guy, you want him stopped. If stopped means he dies, I'm good with that.
Sorry OP for the hijack. Would I render first aid? Not until I know I'm not shot, my family is not shot, there are no new threats (his friends) and 911 has been called. "Did you render aid?" "Yes, I called 911 as soon as it was safe to do so."
