Didn't Willis make this offer a long time ago? Seems like I've heard it before.
Part of it is old news... the part that is new is that he agreed to extend it to those who would turn in "Zawahiri, of course, who is Osama bin Laden`s right-hand guy. You've got Osama bin Laden himself. And then you've got al-Zarqawi"... Evidently he's willing to extend the offer to the capture of those three.
