The first US war crimes military commission trial since World War II opened on Monday at Guantanamo. Osama bin Laden’s driver, Salim Hamdan, pleaded not guilty. The military judge made a series of rulings against the prosecution. He ruled prosecutors cannot use information collected during a series of interrogations in Afghanistan because of the “highly coercive environments and conditions under which they were made.” The judge said Hamdan had been kept in isolation twenty-four hours a day with his hands and feet restrained. Armed soldiers prompted him to talk by kneeing him in the back. The judge also said he would throw out statements whenever a government witness is unavailable to vouch for the questioners’ tactics. More details have also emerged about Hamdan’s mental state. A psychiatrist has diagnosed Hamdan with post-traumatic stress disorder and major depression. When the psychiatrist asked why he did not seek mental health treatment, Hamdan said that he did not trust any providers of medical services at Guantanamo, as he felt they had colluded with guards and interrogators.
