Nancy Drew and the Case of the Missing Porn

Tonight someone stole some porn from the movie store. No I have no evidence but logic tells me so. A man came in eatting a hamburger. He went into the "porn room" and I heard him pick stuff up and looking at it. When he left the building he went through the sensors but he made no sound. Why? I'm thinking he used the foil wrapper from the hamburger to wrap around the sensor. When he got in his car I saw him hold up the wrapper and it wasn't crumpled up like a used wrapper should be. It's sad when stolen porn becomes the highlight of your week.
