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.
