Changes to Military Commissions Act?
Democratic Senator Chris Dodd has introduced a bill to amend the Military Commissions Act of 2006. Some of the changes he is seeking are the restoration of habeas corpus, a narrowing of the definition of unlawful enemy combatant and limitation on the President's authority to interpret the Geneva Conventions. Please do yourself a favor and head over to "Exploring International Law Blog" and read Senator Dodd's remarks. I think he is dead on in much of his reasoning, including this excerpt:

I strongly believe that terrorists who seek to destroy America must be punished for any wrongs they commit against this country. But in my view, in order to sustain America's moral authority and win a lasting victory against our enemies, such punishment must be meted out only in accordance with the rule of law.
