Thank you. I am going to start with the policy question, and particularly how it is framed in the title of the panel, the broader question presented, which is “military commissions, are they lawful and are they worth it?” I think the second part is slightly the wrong question, because it should not just be are they worth it, it should not just be whether they are more convenient, whether they are useful to conceal evidence of torture, whether they are useful to satisfy Congress's Not In My Backyard inclinations. It is are they necessary?
