It is hard to tell if the guy was “spun” by the shot a la hollywood or he had turned around. Camera moves right at the crucial moment
He clearly had turned around and moved toward the cop, whether he had sheers in his hand or what not who knows, but its clear that before shot he did turn around and move toward the cop...
Perp would not stop, was carrying weapon and could have grabbed some stupid female like the one who chased the scene. Shoot the thing with either a taser of a well placed volley of 9mm. He WAS a danger to the neighborhood and the police trying to subdue him.
