The Boards "ban" has no force of law. All they can do is use university sanctions against a person who has a "contractual relationship" with them.
If you are properly concealed (i.e. no one sees it) then there is nothing they can do. They can't search you, if they call the police what's the crime? The police are not there to enforce contract law.....oh darn.
On the other hand, anyone concealing on campus that does have a "contractual relationship" should be prepared to stand up for their rights (i.e. disallowing searches and such).
I'm very vocal and visible on campus about the second amendment. I wear my open and empty holster while handing out flyers and such to those who ask for them and taking every opportunity to write/talk about the legality of concealed carry on campus. Whenever I've been asked if I'm carrying I simply reply "I will neither confirm nor deny that I carry on campus". So far, none has had the cahones (sp) to press it beyond asking and attempting to intimidate me.
For those that are in school.....check your campus rules and regs. You're quite likely to find a section that says (paraphrased and basically) that NO ONE may touch another individual in an unwanted manner, and something along the lines of no force can be used..... and there is often no exception in those rules for the security officers. In fact, if your school has contracted security, it is most likely that the security company policy is STRICTLY to observe and report....NOT to get physically involved. They will attempt to intimidate you, make you think they have more authority than they do, etc., but security companies insurance policies are expensive and almost universally have restrictions like that. Just a little food for thought and a tool for your use as a student or visitor to the campuses of higher education facilities in the state of Oregon.
