Ye, well, e.g. Ted Bundy passed a polygraph. And the Green River Killer did too. But hey, another dude, innocent of course, did not pass the lie detector when they were looking for the Green River Killer. Oops

ALdrich Ames passed a couple of polygraphs.
They only got him because other sources implicated him, and because his finances were notably out of whack for a government employee.

To the best of my knowledge, Ted Bundy was never polygraphed. You are correct about the Green River Killer (Gary Leon Ridgway) and the innocent man (Melvin Foster):

I've heard that they're not very useful with true sociopaths because they require you to be uncomfortable with lying.
Even then, unless they are coupled with a comprehensive psychological evaluation that could identify sociopathy, they could not be considered a useful tool (generously assuming that they have any truth-discerning usefulness to begin with).
