Without looking back to make sure, I believe the animus is directed to the six who were on scene, the one who witnessed the beating action from a desk (via cam) and the chief.
All six on scene are pretty easily guilty of manslaughter, since, from the moment the accused submits, law enforcement is to bring the accused to a safe place.
I wouldn't hang 'em; but they'd be sentenced to the maximum for manslaughter; and they'd be felons. The public can reasonably expect BETTER behavior from law enforcement, than from the general public.
One of the pictures I took yesterday was of a young man holding a sign that said, "I Support the Police: BUT NOT THIS TIME."
I really think he speaks for our community. This sort of "policing" is unacceptable.
If they are tried and found guilty they should be punished....but at the moment no one knows exactly what the cops did or what the perp did....we are relying on what was reported to have happened.
