The U.S. State Department diplomatic cables released by WikiLeaks thus far say little about polygraph policy. You can search the cables by key word at cablesearch.org.

But regardless of what the cables themselves may say about polygraph policy, I think that WikiLeaks' publication of these documents is going to see government officials scrambling to demonstrate that they are "tough on security."

And if past is prologue (viz. CIA after Ames, DOE after Wen Ho Lee [who wasn't the spy they were looking for], and FBI after Hanssen), one way they'll do that is to call for more polygraphs. In particular, I expect that people who work in information technology may be targeted for more polygraphs, whether they are government employees or contractors.

I'd also be surprised if an effort were not made to bring polygraph screening to the Department of State, which has long resisted polygraph screening of its employees, even while, as one of the Wikileaks cables documents, it has enthusiastically advocated polygraph use by other governments.
