Student Protests get out of hand

I'm all for keeping the cost of education down and I do believe the students have a point. But I am really against violence. 

My eldest attends Concordia and this morning, when she arrived at the Hall building early for an Exam, she realized that there was protesting students blocking the entrance.  They were violent and attacked anyone who went anywhere near a door. Other non-protesting students had to rescue them.

Her exam was at 9am. She arrived at 8:15 figuring she'd have time to find the room, get comfortable and be mentally prepared for her exam. She didn't make it to the class before 9:15 after the police  pushed the protesters out of the way and her exam did not start till 9:30am.
