The Boston Globe reports that an FBI translator named Sibel Edmonds, hired after 9/11, found mistranslated memos pertinent to the 9/11 attacks and perhaps even a mole inside the FBI's translator bureau. The result: the FBI fired her, her story has been declared a "state secret", and information that had been released has now been retro-actively classified.
But, make it clear, we are NOT a police state.
