“waited until he was within, say 10 feet? no idea”.
ABSOLUTELY NOT! Somebody who wants to do you harm already has an adrenalin load on; one, or even 3 or 4 shots from a standard police issue firearm will NOT STOP THEM until you have your throat slashed open.
Within the 10 feet if your REALLY good and using a large enough firearm, you MIGHT be able to turn their head into a pink mist if you put one or two right between their running lights.
Oh, I fully agree she shouldn’t have let him ever get THAT close. The point was/is - see my previous responses - that the guy was not approaching *rapidly*, just slowly stumbling along, and *still fairly* distant, considering she already had him in her sights.
And FFS, I was just commenting on that quoted Tueller Drill scenario, which does NOT apply here IMHO. So yeah, I think she could’ve held off for a bit longer to wait how he’d respond to her commands, but I’ll grant that “imminent threat” is a subjective thing - especially if you’re a chick doing a man’s job...
