The charge nurse provides legal cover for the nurse and represents management of the hospital.
The nurse he arrested was the charge nurse. She had her supervisor on speaker phone. When her supervisor told the LEO he could not draw or have blood drawn because he did not meet conditions- that is when he lost it and arrested the nurse. The person you hear on the video saying to the officer “Sir you are making a huge mistake...”- that is the supervisor on speaker phone.
