I read where the police put one on the head of a not-so-bright perp. They attached "wires" to it and sat him by a Xerox machine that had a piece of paper already in it. On the paper were the words "He's Guilty".

Under questioning, every time he replied, an officer would hit the "Copy" button. They then showed him the copy and told him "The machine says you are guilty." He eventually confessed.
