The Terrorist Whisperers
Garry Reed, the Loose Cannon Libertarian - the Touch and Stroke Agents want you to touch a sensor and stroke a keyboard before entering an airplane. All part of continuing putrification of the Fourth Amendment in the name of sekurity.
As quoted in the WSJ (that's Wall Street Journal, not Wealthy Stock Junkies), "Unlike a standard lie detector, the technology analyzes a person's answers not only in relation to his other responses but also those of a broader peer group."
In other words, if you ever want to get onto a commercial aircraft in the future, you must never do anything that will make you stand out from the herd. You must appear to be an interchangeable nonentity of the anthill. You must blend in with the sheet rock.
