Because of recent state legislation and court rulings, eight states now have provisions allowing the carrying of concealed weapons on public postsecondary campuses. These states are Colorado, Idaho, Kansas, Mississippi, Oregon, Texas, Utah and Wisconsin. I have searched for criminal events involving on campus carry, where on campus carry is legal. I have found none. My search was online and not exhaustive. I have found plenty of predictions of the catastrophic effects that campus carry would cause. These predicted catastrophes have failed to materialize. Yea! Once you vote, please take the time to post an explanation of your choice. If none of the choices fit your opinion, please explain it. Sorry, b.net only gives us 7. I can only speak specifically about Texas. If you have a Concealed Handgun License (CHL) or License to Carry (LTC), you have been able to carry on campus, but not in buildings, at 2 and 4 year post secondary schools since September 2013 (maybe 2011). You can only carry concealed, even after open carry became legal on 1 January 2016. After 1 August 2016 (1 August 2017 for 2 year colleges), CHL and LTC holders will be able to carry concealed in most buildings. Private colleges can opt out, and public colleges can prohibit access to some locations. Except for about 260 eighteen to twenty year olds statewide (not necessarily enrollee), all Texas CHL and LTC holders are twenty one or older.
