American experience. The lie detector / produced by Emily Harrold, Rob Rapley ; written and directed by Rob Rapley ; an Apograph Productions film for American Experience
In the early 20th century, researchers made a thrilling new claim: they could tell whether someone was lying by using a machine. Popularly known as the "lie detector," the device was extolled as an infallible crime-fighting tool. Instead, the lie detector became an apparatus of fear and intimidation. The Lie Detector is a tale of good intentions, twisted morals and unintended consequences
