I actually commented on this about a month ago when this happened on the donald win site

My family has been in the NYPD for 30+ years and a few guys from the station and I grabbed dinner that night. One of the guys hadn't seen the video so we showed him and he spent about 10 to 20 minutes watching it over and over again. After watching it one last time he said it's a fake shooting. We didn't get it at first (which pissed him off a bit since there were a couple of detectives in the room), but after watching it a few more times we noticed the inconsistencies.

We debunked the shooting from police protocol alone. There is no way any officer would risk over a dozen lives to shoot an unarmed suspect in a compromised position. Especially when responding officers are right behind her. He did mention that every cop in the video seems to be incredibly stupid. No protocol followed, no crowd control, no communication with the shooter, etc. This video just solidifies what we thought a month ago. I'd also suggest archiving it before it gets taken down.
