there are a lot of resources to help out libertarian-minded individuals who wish to go to law school. The Federalist Society (law) and Phillips Foundation (undergrad) come to mind.
You would be surprised at the number of 2nd Amendment supporters like myself at UI Law. Last month we (the student Federalist Society chapter) brought Alan Gura, the attorney who argued DC v. Heller before the Supreme Court, to speak about the right to keep and bear arms. Over 75 law students attended, most in support of Mr. Gura's views.
We'll have to see how next semester's shotgun raffle fundraiser goes. I have a feeling that will do a lot raise awareness of the firearms on campus issue.
I think the hardest part of challenging university regulations in court is finding a test case - that is, finding a student who is willing to be expelled for a "firearms violation" so that he has standing to bring a suit. For example, as strong a supporter of RKBA as I am, I believe I can better serve the cause by completing my law degree and supporting the cause as an attorney than as a expelled student.
UI is actually better than BSU when it comes to firearms regulations - UI allows students to bring cased, trigger-locked, unloaded firearms on campus, where BSU doesn't allow firearms, period. When I lived at BSU I had to keep all my guns locked in the trunk of my car because BSU made no provision for storage at all. But both schools effectively eliminate their student's 2nd Amendment Rights - I would love to see a lawsuit in federal court charging constitutional violation.
When's that Moscow/Pullman OC dinner happening? Sounds like a good time...
