I can figure out the point of anything

I got stopped in the Bookstore today while walking through the detectors. It has never happened before. I would walk through, the alarm would go off and they would just wave me through. But today, it was different. I had to show and scan my bag, my textbooks, and my CD player. When all was said and done, I was allowed to WALK through the computer part of the store. Never before in my career as a BYU undergrad have I ever seen anyone told to empty their bag when they go throught the bookstore. What was so different about this time?!? I wasn't embarassed or anything, but just a little perturbed because that is not how I wanted to spend 2 minutes of my existance. I think BYU is getting paranoid. Maybe I should give them a reason to check everyone's bags.
