Turns out the guy with the knife and large rock, running around the store, NOT listening to police commands to drop his weapon had a slightly dark secret. He's blind and a schizophrenic. But he's not deaf and when cops say drop your weapon and get on the floor, then you do it. Looks like the cops shoot him twice with bean bag guns and there's no affect. So what's next when the guy is coming at you with a knife? Cops have to shoot him.
