I support allowing students to have guns on campus, so long as their roommates are fine with it, and with the caveat that for gun-owning students, any weapon-, drunkenness-, or violence-related misbehavior results in expulsion. I think it’s silly that someone who doesn’t go to college can own and carry a gun (at age 18 and 21 respectively in most states), while someone who does go to college can’t. And I think the evidence is clear that gun-ownership and -carrying is on balance a neutral-to-good thing, even in this age group. Colleges that do allow guns haven’t had any problems with them.

This isn’t my ideal policy, but it’s better than nothing:

An Arizona lawmaker . . . has proposed legislation that would lift the ban on concealed weapons on public colleges and university faculty members — but only for faculty members who have permits.
