Guest CS, anyone who truly understands the responsibilities of carrying a weapon and using deadly force is a pacifist. Believe me. I've been there. The cop or soldier or person who frightens me is the one who says, "If I'd been there with my gun this wouldn't have happened" or "Just bring 'em on!" These are the people who are are the "if-then" sort. They are thinking "If this happens then I'll do that." They do not accept the fact the it COULD happen and do not think "when-then" -- WHEN (I am shot at, I am attacked with a knife, etc.) THEN (I will respond with my weapon, I will take cover, I will do this other thing). I hope you can understand the difference in the mindsets here, because it's the difference between those who take responsibility and plan for the God Awful (and rejoice when it doesn't happen) and those who act spontaneously and get themselves and others hurt or killed in the process.

No one WANTS the worse, but to plan for it isn't wrong. To assume that you'll act correctly if it happens is wrong.
