Utah State University has allowed concealed carry by permit holders at least since 2002, when Attorney General Shurtleff issued an opinion that state universities were required to recognize state permits. The University of Utah fought it, losing the battle in 2006. Like the University of Colorado, they held the notion that in spite of the Utah legislature paying the bills and the University of Utah actually being inside Utah, following state law was optional.
Shock of shocks, Utah college students must be a lot like Colorado college students (although a bit less violent):
Once again, the University of Utah started out more violent than Utah State University, and remains more violent through this period. Neither school is particularly dangerous. While the trend lines show that there is a slight increase over the period 2003 to 2011 on both campuses, there is nothing that suggests that University of Utah allowing guns on campus after 2006 (or Utah State University after 2002) did anything dramatic to increase violent crime rates.
College campuses in both of these states are reasonably safe, like the campus where I teach. I am not terribly worried about being attacked by criminals, nor do my students worry me in the least. Anyone that I would be much worried about being on campus with a gun almost certainly does not qualify for a license anyway. If such a person decided to ignore the law and misuse a gun on campus — or if the meteor-strike rarity of an insane mass murderer were to show up on campus — I would rather be able to defend myself and my students, instead of just hoping that the police would show up in time.
