Like I said in another comment, I have watched the vids you're referring to and I disagree with their conclusions. I have gone frame by frame and concluded that the events are consistent with a woman being shot and bleeding out from a neck wound.

The shot is not misplaced like some claim, the shooter jerks up the gun before the shot which led to the bullet hittinbthe neck. Many people have reached the same conclusions in fact. The actions ofvarious people in the crowd who mightseem suspicious or actor-like could be equally explained by their inexperience, shock and the chaotic climate in the room.
