A couple of months ago I mentioned borrowing some images from Ken Quattro, who had posted them on Facebook.
Ken is one of the sources appearing in “The Lie Detector,” an excellent new American Experience documentary on PBS. The popularization of lie detectors — which are valid only as an intimidation tactic — has a comic book connection.

The documentary doesn’t touch upon another device, that is also used for truth-seeking interrogation. Scientology’s E-meter.
