Yeah, I'd seen a similar story elsewhere.
Earlier in the week when CBS News reported that Zawahari may be badly injuried or dead, gov't officials took a very cautious position in response and there was debate as to how accurate the CBS report was. As great as it would be, I think those in gov't, probably military are taking a wise course in not jumping the gun to quick.
BTW: Did you see the story on Dubai in the United Arab Emirates on 60 Minutes earlier tonight? You can bet good money that these arabs want bin Laden and Zawahari put down and put down quick after you watch that piece.
