The most despicable use of lie detectors I've ever seen was on the Dr. Phil show. Dr. Phil asked a man who cheated on his wife whether he diddled his kids while he was hooked up to a lie detector. He answered no but obviously a question that is as emotionally charged at that will appear as a lie. This man's relationship with his family, friends and probably any future work relationships were all ruined by a stupid magic trick. The man turned to Dr. Phil and the the former FBI agent who administered the polygraph and start pleading and begging for any reason why the lie detector would give a false positive. Dr. Phil and the former FBI agent were smart enough to know why it wasn't working but they continued be evasive as the man's past and future relationships with his children, family, friend, and coworkers went up in flames.
