Mike we have a poster on here who is well versed in what WSU police can / cannot do. Commander Iceman. Hope he chimes in. While you may "think" it sounds funny, many universities attempt a ban on legal guns be they anywhere on school property. I would ask your girl to find her lease agreement and review it with her. Even if WSU police cannot do anything to you, if they can, WSU may go after your girlfriend for creating a "threat" on campus by inviting you. Amazing how hard scholars will work to oppress others. Often they bend/break the law knowing full well most people just don't have the resources to force them to obey the law.
