“The answer is the charge nurse on scene or should have been called.”
A voice of reason!
Try watching & listening to the bloody video, B4 the cop lunges at the nurse!!! The cop WAS conversing with the nurse’s supervisor via the nurse’s smartphone (speakerphone). Most of that is clearly audible. The nurse also showed him a copy of the protocol the Hospital & Police Dept. had agreed to. Can’t he read?
Then HE went nuts first. Actually, he was pretty damn irrational leading up to that. (”Crazy” takes many forms - if she’d experienced similar B4, she’d likely be scared to death.)
