If by 'policies' you mean to the requirement that law enforcement provide a warranty for arrest when showing up then that's fine. That's within the due process of law but the universities and campuses are not in there buisness of law enforcement and their compliance to what is effectively a form of blackmail is an undue burden of law enforcement on an educational system. It's the job of universities to provide a safe environment for education; it's law-enforcement job to enforce (and follow) the law.
