Mrak is the main admin building on the UC Davis campus. It is now locked from the outside. To enter, you have to show a university ID and be checked on a list of people entering the building. I had to do it yesterday, as did David Copp (Philosophy)—we were both attending somewhat significant committee meetings.
This is surely (and happily in a twisted way) a symptom of that part of Occupy that is now Paolo Freire Open University—aka the financial aid office at the center of campus.
How to stop it. I think we all need to refuse to enter Mrak for any reason whatsoever.
