I read an article somewhere in which a cop told the story of conducting an interrogation using an ersatz lie detector. If he thought the suspect was lying, he'd push a button, and out would come a piece of paper saying "He's lying."

It was a Xerox machine.

That's a scene from The Wire.

The story was around before The Wire.

Yes, in David Simon’s book Homicide: A Year on the Killing Streets, as well as the David Simon series Homicide: Life on the Street.

David Simon also created The Wire.

Fine, it's been around since before David Simon cribbed it:
