This is sort of a sidebar:  why is it that polygraphers think they are infallible?  or condescending?   the way they look at you and the way they make you feel is somewhat "guilty until proven innocent".  the rigmarol of even thinking of talking to an examiner to define your innocence is nonsensical.  In California, according to Edward Gelb, a polygraph cannot be given unless the employer suffers an economic loss. such as theft.  Otherwise no way, no polygraph.  So how does Edward Gelb make his money?  I think he defends the likes of the Ramseys, you remember, Jon Benet's parents.  Money talks and bullshit runs the marathons.  We as Americans can send a man on the moon but STILL can't find the little girls' killer(s).   Eddie just might have an answer....bu he ain't saying. :o
