This article in regard to the Hansen case and how in the beginning they were suspious of everyone but Hansen.

Quote“In order to get brought into this investigation, I needed to take a polygraph given me by the FBI,” says Kelley, who agreed to take the test and passed with flying colors.
But John Moustakas, Kelley's lawyer, says that made the spy-catchers even more suspicious.
“Instead of saying, 'Wow, this guy passed a polygraph, maybe he's actually innocent,' they used that as evidence of his guilt,” says Moustakas. “They said, 'He's the ice man. He's the perfect spy. He can beat the polygraph.' You know what? That's preposterous.”
NVictim,
Yes, quite funny. But also quite sad. Our country's "premier" law enforcement agency refuses to look to it's own for possible bad guys. Not a good situation.
I had contemplated posting a message about this article, but decided on a different one. Glad you did it.
The quote shows that even polygraphers have no confidence that their machine works. They form an opion regardless of the reading from the contraption. Damned if you pass and damned if you fail, it all rest on one person's unqualified opinion. I can see how a polygrapher can be tempted to 'rig' results to suit his needs.
