Article in Pro Publica this morning:

A fellow named Tracy Harpster, a deputy police chief from Dayton, Ohio, has developed what he described as a system to analyze people calling 911 to determine if they are lying or not.
He’s been teaching seminars on his system around the country, primarily to 911 personnel but also prosecutors.
His technique has been used to arrest and prosecute people, and a couple of cases have been challenged and overturned.
This has been described as “junk science”, and researchers have so far been unable to replicate any of Harpster’s claims.
This reminds me of the fairly recent “Voice Stress Analysis” which was also shot down as junk science, and also the claims that you could tell if a person was lying by observing minor, subconscious facial expressions.
