The popular perception that the polygraph is foolproof is so strong that a radio show in LA, while ridiculing the government's handling of this, plaintively said: "Why didn't they polygraph this guy before launching this manhunt."
Sigh.

In a case with as serious national security implications as this one, why didn't the FBI promptly review the Canadian-administered polygraph examination? According to the Washington Post, U.S. investigators were in Canada. In a high priority case such as this one, surely a "quality control" review could have been completed within 24 hours. But it appears that it was only after Hamdani's story was seriously called into question by the testimony of a Pakistani jeweler whose picture Hamdani had falsely identified as that of one of the supposed "terrorists" that the FBI found any "problems" with Hamdani's polygraph examination. Such post hoc rationalizations of erroneous polygraph outcomes are standard fare from the polygraph community. But the real problem is that polygraph "testing" is a pseudoscientific fraud. It has no scientific basis whatsoever, and unless the subject makes a confession or admission, the polygrapher can only guess as to whether he is telling the truth.
