“That’s why I don’t watch “Cops” on TV — somebody will be cooperating, getting down on the ground and some kook will run over, knee him in the back and slam his face into the ground. After seeing more than a dozen of those I never could sit through another show.”
Yeah, usually while three different cops are all shouting contradictory orders at the suspect at the same time. A lot of cops seem to really need instruction in maintaining a calm, professional demeanour. But mostly those kinds of things reflect incompetence and/or over-excitement more than malevolence. Choking a person who’s already restrained, even if they are “resisting”, seems clearly unacceptable.
