When I first watched the video, I thought the detective was either drunk, drugged, or having a complete mental break down. The nurse knew the law, detective didn't have a clue. Nurse was 100% professional, rookie officer got angry, thought he could pull rank, tried to muscle her to break the law. Rookie needs to have assault charges filed, prosecuted to full extent of the law.
.
Good to hear she has an attorney and is filing a major lawsuit against the rookie officer, police dept, police chief. This is going to cost the city big time. Write a check with lots of zeroes.  
.
Police chief failed to ensure all those under him are professional, know the law, do their job to standard.
.
Sad to say the rookie officer is the poster child for the 1% of officers who are not qualified in their job, not professional, need to find a new line of work.
