When I was in CLEET way, WAY back in the day, one of our instructors had been in more than one armed encounters. One of the things he said to me stuck as if it was just yesterday.
He said no matter what that dirtbag is doing, no matter who he is with, no matter why he is trying TO KILL YOU he has friends and family that are gonna stand behind him and scream justice at the top of their lungs and say that he was a good boy who just fell into a bad crowd. The policeman that shot and killed him should have just tried to shoot him in the leg or arm or something and not kill him.
That crap only happens in the movies.
As an LEO, I am trained to fire at center mass and not in the arm or leg. Hell, we even added a head shot a few years ago when the bad guys started wearing body armor.
A friend of mine shot and killed a guy several years ago who assaulted him and tried to kill him. He double tapped him in the chest and he dropped dead. Months later, he met up and had a visit with the dead man's mother. After a lengthy (and civil, I might add) conversation, upon his departure, she said, "ya know officer...I will never be able in my heart to forgive you for taking my son's life." The officer said, "yes ma'am, I know...but if I had to do it all over again, I'd do it the exact same way."
And that's the way it goes down. You shoot to kill. The shoot the gun out of the hand and do the knee cap is Hollywood movie rhetoric. I can't imagine LEO training that adds legs to a target for training.
The stupidity of some people amaze me.
