Watch the video, the guy was running away, twisting backwards to shoot the taser at the cop. So yeah, in the back. Would I have taken the shot? I don't know. Was it a justified shoot- I'd say a jury is going to say yes, then the cop retires off the millions he gets from the city. Before you judge, put yourself in the cops position- the guy has punched you, taken your weapon, is running away and turns to fire at you- you have two seconds to make the call.
