McGill University, following a five-day sit-in in an administration building, announced new rules on where protests would and would not be tolerated, Maclean's reported. In the future, the administration announced, "occupations of private offices or spaces, classrooms, laboratories or libraries, or other restricted areas will not be tolerated. If any type of occupation occurs and the occupiers refuse to leave when requested to do so, civil authorities will be called." In the case of the most recent protest, the university waited five days to do that, but opted for steadily escalating pressure, including blocking wireless Internet and -- toward the end of the protest -- blocking access to the bathrooms.
