On this page there's a longer video of what went down. Cops position is basically, paraphrasing, 'If you don't do whatever I say you're obstructing and subject to arrest. If I'm wrong you have to obey anyway and sue me later.'

Nurse in hard place. She handled it well. If she'd given the blood and the patient later sued, the hospital would have put it all on her for violating their policy. Police tried to coerce her to do just that with their arrest power.
