You shoot at me with a firearm, I return fire. A taser and my partner is nearby, no. I let you go. Real simple.
The shooting was justified plain and simple. You fell for the medias talking point of he was shot in the back crap. Next you will say there was a shot in a parked car.
Fort those that missed the earlier post:
Shooting someone in the back is unjustified, unless they were charging at someone with the intent to maim/kill
