"Often university administrations indulge students who think that it's a legitimate form of expression to occupy buildings and eject deans from their offices, to obstruct passageways, to invade classrooms chanting slogans over bullhorns. Even if you are a First Amendment advocate, there are legitimate restrictions on time, place, and manner of expression of speech. I'm fully in favor of public expression of opinions, but that doesn't mean that I want someone invading my bedroom chanting, you know, build the wall at 3 a.m. There are legitimate grounds for preserving private spaces, and universities ought to have a consistent policy of not allowing students to shut down the university, invade classrooms, take over libraries, and so on."
