on the ground...
you don’t know he’s not still a threat. you do not know he’s not getting back up. especially if you think he’s on drugs. he could be shot but not in anything vital. plenty have played possum.
I doubt many people are so cool as to be accurate enough to hit a small spot when the guy has a knife. Most just point and shoot. But I see your point. Knee cap him. But, as I said, under stress those knees would probably look pretty tiny.
Otherwise, if he’s down, don’t shoot again unless he starts to get up.
Possum?...so you shoot him on the ground after pumping a couple rounds in the guy? Seriously, you can’t defend trigger happy idiots like that. He had 18 previous complaints, one that cost the city 350k to settle. He should have been kicked off the force a long time ago.
