The horrific tale of Bradley Manning's incarceration reminds me of this scene from the 2002 film version of The Count of Monte Cristo:
Dantes: Monsieur, I know you must hear this a great deal. But I assure you: I am innocent. Everyone must say that, I know, but I truly am.
Armand: I know. I really do know.
Dantes: You mock me?
Armand: No, my dear Dantes. I know perfectly well that you are innocent. Why else would you be here? If you were truly guilty, there are a hundred prisons in France where they would lock you away. But Chateau d'If is where they put the ones they're ashamed of.
Why are we so ashamed of truth?
