U.S. polygraphers questioned accuracy of tests on detainees overseas

13. It is only in the rarest of circumstances that I have ever used one

And it's very rare indeed, but if I have a client in a case where the evidence isn't strong and I know the prosecutor would probably rather not pursue it but for an angry victim or public opinion, I have in a handful of cases had the client take a private polygraph (not stipulated and not revealed to the state ahead of time); if he passed I gave the results to the prosecutor- not as evidence in the case but as something for the prosecutor to "hang his hat on" when explaining to a victim why is was punting a case. In those rare cases it has had value in that regard. Notice none of that has anything to do with using a polygraph as evidence of truthfulness.
