These cops did violate the very simple procedures though. They were required to assess the bleeding person even if he was the culprit. So long as he wasn't actively resisting, they were obliged to check his status & wounds. They did not even look at his wounds. They cuffed him and dragged him as he screamed in pain. They continued to "read his rights" even after he'd clearly lost consciousness. Only then did they consider that he might actually be telling the truth. No call for an ambulance came until after he'd stopped breathing.

The one mitigating fact that gives them a TINY bit of grace is that he'd been removed from the actual crime scene. The expected trails & puddles of blood were elsewhere. Still? What they did was criminal. They all should get 2x the sentence Coven did, especially since he followed procedures to the letter.
