This is a total misinterpretation of events, rather a distorted version as viewed through a deeply biased filter. The perp was interfering with law enforcement so he got what he asked for. Submission techniques are on an ascending scale: if the light stuff doesn't work then you ratchet up until the perp complies. There was no police brutality or abuse. You're ignorant of police procedures. Bo Ranking was doing the job he was trained to do. Thank you Bo Rankin.
