I did this years ago when i was brand new to DNMs and i thank my lucky stars that i did not get caught. Please if you are at a university, do not have your drugs mailed right to your university P.O. Box. They are much more likely to search, you have less rights due to your contractual obligations with your school, and the charges will likely be worse at an educational institution. The fewer of us that get caught the better.
I don't see how shipping it to a university has anything to do with him getting caught. According to the article the cops already suspected it was a controlled substance before it even arrived at the university. If this guy was getting it shipped to his house he would still have been totally fucked. I think the real lesson here is don't order 1+ ounces of marijuana at once.
