I was perusing the closed thread and saw the following post by South Narc:
I'm curious about the experience base of everyone posting. Who has ever actually pointed a gun at another human being with the intention of shooting them if need be?
I have a question about this statement, completely different from the closed thread. Is this just a manner of speaking, or are there scenarios where a citizen would point a firearm at a person without first having decided to shoot them? Bill Rogers makes both a physiological and legal/moral argument that a muzzle never covers another person until you are going to shoot them. The physiological part being you are just as fast to hit them from a confirmed, extended ready with the muzzle depressed below the threat as with the muzzle on them, and even faster from the ready as opposed to on them if they move. The legal/moral argument being that rule two is the primary safety rule, and we don't cover people with a muzzle until we have decided to shoot. While I am not LE, apparently that is the same philosophy as to not covering people with the muzzle that they teach to LE.
I haven't had a chance to take a course with South Narc yet, so perhaps this is something he covers there.
