Medical professionals do refuse! If you remember Alex Wubbels a nurse who refused to do a blood draw stating that she would not unless the patient was under arrest, a warrant had been issued or the patient had consented.

She was arrested, although not charged and was later apologized to. The cop was fired and it also lead to Utah changing its blood draw laws.
