Colleges\Universities don't have to follow local, state or federal law if you are a student becasue they are responsible for your safety while in their care. This is ilegal and why I included the link to fire.org. By stare decisis and lack of concerted visible legal challenge accepted by their local legal system. They are also cash cows who make generous donations in their own best interests. You are dealing with essentialy soft totalitarian entities. So don't scare the natives.
Very often the local judicery and police is fine with this and defers to it. You also need to understand how quickly your right to a lawyer and your constitutional garuntees have no power in the US constiutional self exempted utopian sovereign nations called college or university. There is some quasi judicial tap dancing that covers the right of these farces to ensure everyone's saftey by adjudicating all violaters as guilty upon complaint with no recource to local, state, or federal due process unless you have access to lawyers with experience beating them into subission.
When you sign your student acceptance contract you sign away your rights while you live in their tiny totalitarian states. Try wearing a Glock T-shirt with a picture of a Glock on one side and "gun control is using both hands." on the other side on most campuses today. You can get kicked out of the school for being a teorrorist the next day, arrested for hate speech then dismissed, and even arrested and forced to take sensativity training, ongoing counsiling and accept 1 year of legal probation for public intimidation and harrasment. Magicly it will follow you to all of your background checks after graduation. It's just about as bad if the T-shirt says "I Heart Jesus" now on some campuses.
Keep the knife out of sight in your underware, never talk about it, or just don't push the issue and leave it at home. You cannot beleive how crazy campus legal systems and regimes will get to punish you for the smallest ideological infractions these days. Then hide under a table the next moment while a nut job blows you away along with everyone in your class. Welcome to the sovereign nations of utopian bliss and "right minded" thinking.
Why don't you just get an online degree from an accredited providor if you are worried about nutjobs assaulting you on campus? If it's meeting girls. Just remember on many US campuses she needs no proof to accuse you of something and you are guilty from that moment. 2009 TitleIX money was conditioned on a DOJ updated directive that all accusations against male students by female students be weighed against the preponderance of evidence rather than guilty until proven innocent. Don't be a bad or cheap date, or PO your girlfreind in effect. Her word is the only word the campus needs to ruin your life if they want to keep their federal funds. And the womens studies graduates who often run the campus sexual harrasment centers and festoon their legal units love it. The DOJ author of the updated missive is one of those wymans studies and legal school graduates.
