I'm not sure that I have heard of him being in trouble.
That's not at all the same as saying "oh, he would have guns in his car while it was serviced" and just assume there's nothing strange about that factoid. I'm not sure what the student code of conduct says about having a firearm on campus, but I would think there is explicit language about whether or not you can have one and if so, how it must be stored, etc.
At any rate, I don't even know if that story above it true. It surprised me and I really don't think I'm alone.
