Cop was in the wrong from this first, as there shouldn't have been a choke hold to begin with. I think they were saying that was even policy? I'd like to see a manslaughter charge, personally.
Ya, the guy was illegally selling something, and the cops had every right and duty to take him in, and he really shouldn't have been standing there screaming his idiot head off instead of cooperating. Still...choke hold is a no-no.
