For proof, if any is needed, I point to Jack Ruby's "lie detector test." He passed too.
Not in these circumstances. This situation has an allegedly unstable schizophrenic man trying to get away with creating an outrageous hoax. It would be very difficult to claim that a man who was so stressed as to cause his commitment was also able to calmly fool a polygraph at the same time. Funny how the polygraph missed that chronic stress. Yates also had a corroborating witness.
They're not that unreliable Drew. If they were that unreliable they would just not use them at all. Besides, the polygraph that FBI gave Yates satisfied the FBI agent who told Dorothy Yates "It showed he was telling the truth". Hoover also said they were having trouble discrediting Yates' story. If Yates was that bogus you would think the FBI wouldn't have any problem proving it.
Read DiEugenio if you think the polygraph given to Ruby was a fair comparison.
