If true, there goes the murder charges...against the bikers at least. It sounds to me like police snipers were doing the shooting, not bikers. It sounds like they were firing high powered rifles into a crowd of people in fact. Plenty of reasonable doubt there.
2. Gang member involved in concert at a felony.
It was a bar fight until there is evidence that proves otherwise beyond a reasonable doubt. So much reasonable doubt. This will go nowhere.
If the newer reports are right, and all shot by leo, this might be far from being over,.
It never has made any difference what happened other than there is a dead body. The requirement is the production of a death certificate. What will be hard is the link, You go to a game and the crowd wants to kill the ref. He gets killed. How many get to be arrested.
