Current Students: Why Is Campus Still Restricted With No Protests Happening?

Sorry, I'm sure everyone's tired of hearing about this, but I'm an alum who regularly used CU's libraries. A godsend in a city where you can no longer find a place to read past 7pm, basically.

Anyway, I was wondering if any current students could shed light on why the campus is restricted despite (to my knowledge) no protests, no recent political upsets, etc.? Is there something I'm not hearing about that's happened? Are they anticipating something because of...well, why?

Thanks
