11. because he was head of an agency that asks all its employees if they've ever had an affair.
i may be slightly overstating the case as i'm not sure *all* cia employees have clearances and i'm not sure *everyone*who gets a clearance gets asked that question.
i do know that *i* once had a secret clearance and i *was* asked that question.
had the polygraph reader felt i was lying, i would have been denied my clearance and i would have immediately lost my job because i was working on a secret project and was of no use to my employer without a secret clearance.
you can't credibly run the show at a place like that if you fail the test that you insist every low-level employee take and pass.
just to note, the correct answer is to tell the truth, whatever it is. they're not there to particularly judge your morality, they're only there to determine your vulnerability to blackmail. so an answer such as "yes i did and i immediately posted it on facebook and i'd do it again" is fine as long as it's the truth. in any event it appears patreus failed on all accounts as he not only had an affair but also tried to keep it secret, which made him officially vulnerable to blackmail.
