On impunity:
The Military Commissions Act seeks to accomplish its objective of granting impunity through three tools. First, it redefines "war crimes" into a series of specifically chargeable offenses, of which two, "torture" and "cruel treatment" are most important for these purposes. Second, it makes the restatement of these crimes retroactive to September 11, 2001. Consequently, a series of criminal offenses under the War Crimes Act will disappear retroactively when the Act goes into force. Third, it strips courts of jurisdiction over habeas corpus petitions and forbids litigants to cite the Geneva Conventions and related international and foreign law in those courts, in an effort to blind the courts to the law which the Constitution obligates them to enforce.
The initial draft makes clear that the White House sought impunity for crimes arising as a result of the use of three techniques that the Bush Administration (and, from the remarkable working of one of Bush's press conferences, Bush himself) authorized and which constitute grave breaches under Common Article 3: waterboarding, long-time standing (or as it was called by its NKVD inventors, in Russian: stoika) and hypothermia or cold cell. The use of these techniques is a criminal act. The purported authorization of these techniques is a criminal act. The larger effort to employ them constitutes a joint criminal enterprise.
Go ahead, read the whole thing. I'll include one more quote -- the conclusion:
The legacy of Nuremberg and the solemn undertaking that Justice Jackson gave for the United States at the opening session, are under assault by the Bush Administration, which has embraced a radical world view that rests on a cult of power and a disdain for law. And fundamentally, this Administration has a notorious allergy against accountability in any form. But this conference is evidence that the spirit of Nuremberg has not been extinguished in the United States. And indeed, the flickering candle that was lit at Nuremberg has developed into principles which form the heart of the international legal order. We bear witness to those principles with this conference.
