FYI--The full body camera footage is out there now. Not just the arrest, but what happened before and after.
The officer was directed by a detective to stand down because he realized that the hospital always takes blood samples when a patient is admitted, so law enforcement would be able to get access to it regardless. For whatever reason, the officer ignored that directive and arrested the nurse anyway. He and his supervisor then spent twenty minutes trying to figure out how to get out of the situation, forgetting at various times that they were being recorded by the body camera.
These situations are never black and white. Here, though, we've reached the point where this particular officer no longer deserves the benefit of a doubt.
He also threatened to start bringing them all the transient patients as retribution.
