I know a fair amount of people, mostly LEOs who've had to kill bad guys. I know of only one who has had a great problem dealing with one of his two shootings. This was in a situation in which he killed an innocent man, although because of the situation, it was found perfectly justified by both his dept., and by the D.A. It was just a very tragic situation. He had major problems with it, although about four years earlier, he'd had to kill a roober in a warehouse robbery, in which the robber actually fired a 12 ga at him. He told me it didn't bother him a bit to kill that robber SOB.
Another good friend of mine, in an off duty incident, had to kill a bad guy, and he felt no remorse whatever.
I know another LEO who had to kill a psycho who had just decapitated another cop. The psycho was then trying to kill the LEO. The LEO wasn't sorry a second.
I know a woman, civilian, who had to kill a man who had broken into her home and was attacking her. She was extremely angry at the suspect, but was not sorry a moment for killing him.
I know two other civilains who had to shoot for their lives, and they aren't a bit sorry, as they were pushed into it by the crimnal's actions.
My experience, kinda opposite Robert's is that the people I know, who've had to kill in defense of their lives or the lives of innocent people, are not suffering trauma from it. Only the man of whom i wrote above, who shot the innocent civilian.
Anecdotal, of course, but that's what those people told me. All these were southern Kalif. incidents.
BTW, LASUR5R, I know exactly what you're talking aobut with those little sh!thead gangstas.
FWIW. J.B.
