As anyone who has actually worked in intelligence, defense personnel, or surety programs could tell you, the immediate action when a person is suspected of having become unreliable or breaching security is 'Suspension,' which is supposed to give the authorities six months to investigate the problem and then either restore, continue the suspension, or proceed to revocation. Revocation is a final step, not an initial one, and only rarely involves prosecution.
It's abundantly clear that every DUmmie claiming experience and familiarity with clearances in that thread is lying his or her ass off.
