...that's part of the story. Thing is that the autopsy isn't in and everybody wants to hang the cop.
...he was talking, if you can talk, you can breathe.
...ya don't know how many cops it took to bring him under control or if they had let him up once and had to subdue him again. The video only shows part of the story.
...it is far more likely that he had a heart attack that was induced by meth or some other drug and then trying to whip the whole police department.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
