I know for a fact that most government top secret clearances don't require a polygraph. Not that it means shit, since polygraphs have never been proven to prove anything. I just hate when I see things written by "credible" people that will be taken by fact by hundreds of people when it is not entirely true. Working in environments where all of the fine details are rarely shared, you see this a lot in the media. Law enforcement in general (Anywhere from city to FBI) is known to give polygraphs before a conditional offer of employment is given. However, this is not the case with all agency's.
