Actually, the pepper spray started after the gun came out, kind of a defensive reaction. I am pretty sure the man saw the gun, totally did not expect it, his hands probably started reacting on their own. If you notice the other hand, it has started into his chest as a protective measure, and he is taking a step away from the guy.
Totally unprepared for the gun to come out, and trying to distance himself. But the shooter knew what he was doing and hit him with a head-shot, no attempt at shooting the can out of his hands. The shooter meant to kill.
....”The shooter meant to kill”...
Well that’s what armed Antifah does do.
It's been posted here on FR, that the shooter had pulled his gun, and was told by the victim, and others at the scene to "put it away."
