I believe the proper procedure is to never point a gun at anyone you don't intend to kill.
When I was active duty air force they regularly train hand to hand and disarming someone with live weapons that are unloaded. The excuse I got was they didn't have money to buy realistic fake solid plastic ones used by martial arts people.
One time in Afghanistan I got a tent all to my self, for weeks, it was great, then one day it filled up with security forces, which are air force cops. After their chief left they all immediately pull out their guns and started cleaning them, nothing too scary. Well after about 20 minutes of cleaning, the cleaning started turning into start playing with them.... Ever have a nightmare while you're awake, that's what it's like.
Another good one I got to go to a navy range to qualify once because of extreme lead contamination abthe air force range. So the answer was to go to the navy range. Got to the navy range and it was completely shot up. Dozens of holes in the ceiling, chunks blown out of the concrete floor, the shooting lane dividers were just plywood, they had bullet holes in them, the walls down range were all shot up, were taking people missing their targets by like 10 to 90 degrees.
There were even several holes in the front wall of the range, you know approximately 180 degrees away from the targets are. How did people that incompetent with a gun ever make it to any duty station?
You think that maybe someone went crazy and shot up the range, yeah maybe but not unless they had a rifle and pistol, were able to reload both several times and moved all over the range and firing at least a handful rounds up at the ceiling from every shooting lane. Made me very nervous around navy people with guns. The navy probably shouldn't be allowed to have anything smaller than crew serviced guns. If they need a guy with a rifle or pistol for some reason, get a marine.
