"I got out my taser and snapped his face to hell" (one of the officers). Tasers electrically burn a person. The officer was tasering him in the face.
The video is fully outrageous. At one point they had as much weigh on him as if they had set a small block Chevy V8 on him as he said over and over he couldn't breathe.

The man was going to die. The claim that he wouldn't put his arm behind his back as reason while putting what looks like 500+ pounds of weight by those fat officers on him meant at that point he was going to die. The only manner he had left to try not be so crushed by the weight was his arms.
Lay on concrete and put that much weight on your back with your arms behind you and see how long you live. So they had given him the choice of being immediately crushed or or stay alive a few more seconds if he didn't. He could agreed to be killed or be killed for not agreeing to being crushed.
Clever Catch-22 to kill a street bum. Let us crush you to death or we will crush you to death for refusing.
They didn't just grab his right arm and put it behind him. The coroner said his death resulted from being crushed and beating injuries.
From what I see, he was doing nothing illegal to begin with and the first officer began by pricking with him. I would have gone with manslaughter if I were on the jury, but would have to watch more carefully as to which officer(s) that would apply.
The video speaks for itself.
