Move to Colorado, turn 21, get CHP, forget about any silly university policy due to preemption.
When our new laws were being debated in the legislature, the university and the student government tried to make a big deal out of the notion that people carrying guns would stifle academic freedom. Apparently people like me are going to use our guns to make points in the classroom; agree with me or else. But of course that would be illegal whether or not CCW was, as brandishing, assault, etc.
Anyway, the good guys won in CO. And there are other states with similar laws, like UT, I believe.
