Wavemaker, you are starting with a false premise. The current Regent's policy doesn't mean there are no guns on campuses nor that violence is prevented thereby.  Just think about it logically, you and the Regents are stating that someone willing to commit a violent felony, with decades of imprisonment as the penalty, will be deterred by a misdemeanor trespassing charge or, if a student, not getting their grades that semester. It's a puerile argument.
