First post here, and it is a question to anyone: :)

I have a polygraph test coming up, to be administered by a contract employee of the federal government.  It will be on government property, and so (I guess) covered by federal law.

My question: is it legal for me, to the best of anyone's knowledge, to audio-record the interrogation for my own purposes without the knowledge of the polygrapher?  I would, of course, be privy to the fact that the encounter was being taped.  I don't see it as any different that someone wearing a wire to get damning evidence against someone, but I was interested in community opinion.

Thanks for your help  ;D  BTW, I have read Lie Behind The Lie Detector twice, and I find its information quite beneficial.  I would recommend it to everyone here :)  Cesium...
