Take the first 10 try them for treason and put them in front of a firing squad.
Firing squads are over too quickly. These traitors - to a man - need to be convicted for treason, hung by the neck until dead, and then the carcasses loaded into gibbets surrounding CIA's HQ parking lot, as food for the crows and a pointed warning to the rest of the intelligence community.
Traitors don't deserve burial in soil they betrayed, except as bird shit.
