It was a stupid decision to charge him. Restrain him, yes, because you don’t want to stop the emergency workers from doing their job. But charging him was absolutely insane.
I doubt the Dad would have interfered with the EMS. He just needed to be there. I used to work at an ER. During codes we would try to take people to another area. Most were more than willing. A few insisted on staying and we let them. I never had one of them interfere with care. The father should have been supported if he refused to stay back or released immediately afterwards if he was out of control. This officer needs to ask...if he had been in his shoes...what would he have done.
