Tumbling in Albany, NY, USA
Knowing just how feeble these scraps were as evidence against Dreyfus, the prosecution decided that they would not be shown to the defense but presented to the judges alone. Du Paty was recruited to write a ‘commentary’ on this additional information, explaining how they established the guilt of the accused. If the judges themselves had misgivings about the legality of what was being done, ‘national security’ would be invoked as a justification. Even in a court martial held in camera, the secret service could not be expected to reveal either its methods or its sources.*
