Honestly I didn’t see anything on that video that is not normal restraining from a police officer with an unruly suspect. Cuffed, face down with a knee in the back or neck area. It’s not like they were throwing punches or beating him with batons? And the statements made that if you can talk you can breath is also the normal prognosis. Something else happened with this guy, either medically or pharmaceuticaly. But it really doesn’t matter at this point because if they don’t crucify the cop it will just get worse.
