I agree. While I don't particularly like the annoying Copblock dickbeaters and their cameras, this citizen did a good job capturing what he did. I think the video is what seals this case, without the video or witnesses, this guy could still be on the streets potentially as a murderer. I say potentially because even he deserves due process and he hasn't been convicted of anything.
The guy could be a total shitbag but I feel bad for him, especially seeing how his body reacted to those shots. He didn't look like the most physically fit individual by the way he was running prior to those shots. You can see him go up on his tiptoes upon impact. Several of those rounds found there mark and that guy suffered no doubt.
