I am kind of surprised by the university's rather gentle response to that person breaking their rules. It seems to me they are being as nice as possible about the situation. Obviously, your friend shouldn't have told anyone that he was breaking the rules, but that's in the past now. I'm with the others here that say don't give a response, or give a response saying "I will respect your rules...blah blah blah" and continue to carry.
I think raising a further stink won't be good for him/her. Might be best just to kiss their butts and thank them for not throwing him/her out, and just carry on making sure he/she never gets caught.
I think the gentle response is because the individual did NOT admit to carrying, but was rather discussing his/her waiting time for the LTCH. I was wrong when I stated earlier that he/she had admitted to carrying, but just simply admitted to having a license!
