I would walk up behind them and tell them to meet me behind the store immediately. There i would explain that we were being watched by the government and weren't safe to talk inside. I would then take them to a safe location, but knowing the government they would capture the person from me no matter where we went. I would eventually find the holding cell where i would knock out the guard with chloroform. I would remove the key from his belt and unlock the cell, at which time i would poop on their shoes and run away. Don't shoplift people, i'll poop on your shoes.
