Sheer insanity and dangerous.
A better rule would be: whenever necessary.
NYC is already a libtard’s wet dream. Just imagine if you turned loose a couple dozen super left libtards, with unlimited power, lots of taxpayer money to blow, and no normal moral constraints. That’s NYC now. The school system is especially vulnerable to their idiocy, since the control of city schools was handed over to the office of the mayor. BAD move. People are gonna get killed if the police are taken out of the schools. There’s already absolutely no discipline allowed in schools, particularly for black or Hispanic students. That’s right; kids can do whatever with impunity, teachers are not allowed to stop them.
