Bull####.. he didn't assault her.. he was calm when he said.. OK, that's enough, you're under arrest.. then she had the hissy fit reaction and tried to get away and resisted..
Bob, he arrested her without cause. She was simply doing her job and complying with hospital regulations. Cop didn't like that, thought that he should be above the law, and took her down. Now you might think cops should go around arresting people for following the regulations of their job, but I do not.
Had she turned around and allowed herself to be arrested, that cop would STILL be in the wrong, and the police department would STILL be open to a lawsuit. Even without the video, the cop was still wrong and still overstepping his authority.
What should have happened is that the cop went and got a warrant. The reason he didn't is because there was no cause for him needing that blood sample. There has been no explanation that I've seen as to why he even asked for it, let alone demanded it, let alone assaulted and arrested a nurse who wouldn't give it to him. He thought he could bully this woman into compliance and now he gets to pay the price for that.
Did you see the video of him bragging how he'd get even with the hospital and his other remarks? Cop was in the wrong. He's a seriously bad cop. He needs to move on to other employment opportunities that are better suited to his temperament. The end.
On a related note, that "blue line" bull#### needs to stop. I get it - cops put their lives on the line, brotherhood, blah blah blah. But when you see your fellow police officer get out of control and overstep their authority, the smart thing to do for the whole law enforcement profession in this country is to set him down and bust him out. How are we supposed to trust our police officers knowing that they'll look the other way when one of their own is abusive and breaks the law? How can we trust them knowing that they will not protect us if the assailant is another cop?
