That depends on what your definition of "unique" is

CIA chief Porter Goss says that "[t]he CIA's interrogation methods are "unique" but don't involve torture." (via CNN)

If that is so, they won't be needing that exemption from the McCain anti-torture bill, which prohibits "cruel, inhuman or degrading treatment or punishment," will they? So we can just go ahead and approve that bill, right Mr. Goss?

Also: Compare Powell's former aide Larry Wilkerson: "There's no question in my mind that we did. There's no question in my mind that we may be still doing it...There's no question in my mind where the philosophical guidance and the flexibility in order to do so originated -- in the vice president of the United States' office... His implementer in this case was [Defense Secretary] Donald Rumsfeld and the Defense Department." (CNN)
