At this moment, it is NOT GOING WELL. They were originally closer on my side, and the collector exemption is difficult to marginal at best.
I have a lot of mitigating factors on my side right now, but the Director of Security is under the impression that possession of an automatic knife is a misdemeanor- and he might be right, and he will be right unless I can argue the collector exemption- which is looking increasingly bad for me right now.
At this point I can say that I will almost definitely be fired. What I'm scrambling to save right now is whether or not I will be allowed to remain on campus- for some reason it has become impossible to find regulations about this sort of thing. SHIT. I am utterly screwed. It's at damage control at this point- all I can really hope to salvage is being able to remain on campus and not having criminal charges pressed.
Best case: Out of some miracle I manage to retain my security job with no more than administrative discipline, the University does not kick me out of the dorms, and I am not disenrolled from school.
Worst case: I am fired from the security job, lose my other university job as a columnist for the school paper, am kicked out of the dorms or out of the school, and have a misdemeanor on my otherwise lily-white record.
Most likely: I am fired from the security job (Or possibly allowed to resign), keep my other job as a columnist, and receive no academic punishment.
I honestly cannot predict what's going to happen, but to be frank, I'm scared. Nothing like this has happened to me before, and I'd really appreciate any help and prayer you guys can offer me.

I hope to be able to argue my case in front of the Security Director and end it at that, but if not, I will probably have to argue it in front of the police and possibly a Student Senate Court. I don't know where to begin. Frankly, if anything approximating the worst case happens, this will ruin my life as I know it. And I am really scared right now.
I accept responsibility for this error in judgment, and for failing to do adequate research on the legality of my EDC, so if you guys could stop making comments about "Why didn't you know better?" or "What did you expect?" I'd feel a little better. I know that I did something evidently illegal here, and in the end I'm the only one who can take responsibility for that, and I choose to do so.
I don't think it's right that things should go this way, but evidently, it is legal, and the law has to be enforced equally, regardless of whether or not the law is just and right, it is fair. I am still an objector to this law, but I did know what it might mean.
The one ray of light in the current situation is that I called my Army ROTC instructor to report the possible legal violation, and AFTER he stopped laughing, he told me the story of the time he was handcuffed and detained on campus. Evidently it will not be a serious legal issue for ROTC participation.
