armchair hindsight is 20-20, but its pretty clear from the get-go that the bigger cop who wrapped up on him first just flat out screwed it up in the first 7 seconds. choke hold, on top, on the ground, with partner then joining. C'mon.
after that, its a mess, the big juice heads got tired, and the inmate was clearly defiant. Wrestling around on the ground at that point? Eff that. biting, sweaet, blood, hands close, weapon... hell no.
