While your comment is true, the people in that university building may not be students. The Fox reporter on the scene said it was a dormitory that's rented out to non-students during the summer.
I'm interested in seeing in-depth reporting about who these protesters are and what they do for a living. They seem able to travel anywhere in the world at any time and spend days or weeks behaving like lawless jerks and breaking other people's property. I think this is much more than a simple movement of air-headed students. If anyone actually investigated I'd bet they'd find links back to Soros and Maurice Strong among others.
In one CNN report, I could of sworn I heard a police officer say “TAKE OFF YOU HOSERS!!!” (sarc)
They were a group who came from Montréal. You are correct about the residence; most univerisities in Canada rent out their dorms during the summer months.
