It does not appear that the protester was looting or attempting to assault anyone.
If that is the case, the officer was way out of line.
He will likely be subject to the laws that would apply to you or I if we were to point a gun at someone and say, “I will expletive kill you.”
Wait. Are you saying I shouldn’t do that to folks? : )
The cops were trying to get the crowd to move to a different location. Taken in context, the cops words were no more meaningful than mine when I’ve said I was going to kill someone. If the cop meant it, videoprick would be dead already.
Sorry, but I’m all out of sympathy for wannabes running around Ferguson trying to identify with black thug criminals at night. I’d vote to shoot a dozen just so this crap will end.
