One big issue I see is that a lot of schools have their own police forces. They are legit police forces with power to arrest, etc. On the surface that seems like a good idea because when you are in a city, or even a rural area, you may not get the services you need/want from the city police or sheriff. The flip side is that these police are employed by the university so they have no independence. A mayor may be able to assert some influence on the police department but the president of a university can terminate the officer.
