He wouldn’t have gotten away with it. Forensic medicine can tell both where a person was shot from and from how far away, and it was pretty obvious that the officer was under no threat. However, the video at least means that the trial is going to be very short!
Police shoot 12 year old boys in parks, unarmed men in Walmarts, authorized concealed carry people at Nevada Costco, he most likely would have walked on this absent the cell phone video. After all, he planted evidence to make it look like the victim was armed with his taser. Claim 'fear for my life' and that would be all it took. And anyone who doesn't believe that is just fooling themselves.
