If the public hadn't been present and recording footage I'm sure the report would have ended up a lot like this.

My question is what are the other perps who are being detained supposed to do? If the other kid sitting on the floor would have went for an officers gun
after the shooting would he have been justified in defending himself with deadly force? If he got up to run would they charge him with resisting? I don't think I could continue to take verbal orders from someone who just shot another person who they are responsible for protecting. I would have been looking for ways to overpower one of the officers to obtain a weapon in hopes to even the odds.
