It isnt just the principals it is the teachers as well. We had a juvenile who broke into an 80 yo man's home and beat him for his wallet. Putting the old man into a coma. I went to his school to take him into custody. The female teacher tried to tell me I could not take him until they notified his parents as that was school policy. I informed her that I could care less about school policy, that the boy was under arrest and going with me. And if she interfered she was going with me as well, In handcuffs for obstruction. The school principal called to complain, my Chief told him the facts of life and then he called the school superintendent and told him to educate his people better if he didn't want the being arrested.
