I am thinking that the rumors were posted by either Scheuer or the PR arm of cbs to get viewership up real, real high tonight! It is possible.
Well, I don't have a pr firm, but I do have an OPINION:
The release of the UBL video tape was a GO signal.
Go where, attack where -- well, one can only speculate.
The various UBL graphics in a number of islamist and/or
jihad forums are showing support for UBL and his message.
That's my 1.5 cents.
