Danger, Warning, Will Robinson!
This is the same rubbish we hear from the Global Warming advocates.
As in "Everybody accepts that the science behind the lie-detector is accurate. (Except a few skeptics, and they are nutjobs)"
Sorry the polygraph is a voodoo interrogation device. If few of it gets the subject to confess, OK. But you can't rely on the results it generates.
Lie detectors only work if the person being examined BELIEVES they work.
Thus they're beatable by people that understand this, and people that are just flat out nervous and scared of the machine will be recorded as lying when they're telling the truth.
