I suspect that with men like General Petraeus, where honor means something - losing your life is secondary to losing your honor.

The United States attorney in South Carolina was a Barack Obama appointee. Politically, he is to the left of Mao Zedong.
Even someone as lowly as an assistant U.S. attorney has to undergo a background check, and you're asked a series of very invasive questions, and you're expected to tell the truth and they're under penalty of perjury. And you're asked those questions so you can't be blackmailed or extorted.
If you were summoned for jury duty and you didn't show up, what would happen? You'd be in jail!
