The campus was invaded by armored police officers. They threw actual tear gas into crowds of students. They SHOT students with rubber bullets. They beat slower-moving students with a baton. I saw a group of cyclists being herded down the sidewalk. A cop reached out and pushed a woman on a bike. She turned around and pushed her bike at the cop. Next thing we knew, he grabbed her by the face and slammed her down on the concrete.'

Its on their own campus and they weren't doing anything illegal.

I've seen many comments about how they should have gotten away from the police and not provoked them, but after speaking to people who were actually there it appears that the police had actually blocked in the campus on all sides and they were unable to leave just like what happened in London.
