This is absolutely awful. A main who is chained and drugged is being beaten by Maricopa County officers (yes, these guys report to Arpaio).
We can award extra points here to Arpaio who is saying how incredibly difficult it is to detect these incidents - Just think, he says, how much video we would have to go through. But my untrained eyes show in every case at least 3 and sometimes many more county employees looking on. Apparently none of these folks reported the incident. Which means that unlike what they are trying to portray here as an isolated incident due to one bad apple, this is a systematic culture of violence against citizens that pervades the whole organization.
Double extra credit for the implication that none of the onlookers who watched a violent felony in progress and who are nominally law enforcement officers will be punished for covering up the incident (brief opening commercial)
