Police in Radnor, Pennsylvania, interrogated a suspect by placing a metal colander on his head and connecting it with wires to a photocopy machine. The message "He`s lying" was placed in the copier, and police pressed the copy button each time they thought the suspect wasn`t telling the truth. Believing the "lie detector" was working, the suspect confessed.
