Yes Lethe:

I agree with you for professional fraud is a substantial danger to our society.

Perhaps we should also track and identify those who manufacture the props of the polygraph con.  Are the companies that manufacture polygraph machines publicly owned?  Who holds the stock?  If these companies are privately owned, the question is by whom?

George, I cannot find anywhere the liability status of any detection of deception ‘technologies’.  Who is legally and financially responsible when these infernal contraptions inevitably yield the wrong results?
