I am betting on fairly coordinated suicide bombings or shooting attempts in several cities at once. And there is no other day like the 4th were large groups of people are gathered together all across the country.
I still believe that as soon as these guys get their hands on a WMD, Israel will be the first target.
We had 40 terrorists land on West Coast. How would they communicate? Stolen cells. How far away is LV from LA? Not far at all. How plausible is your scenario? Unfortunatley, very.
CNN, Drudge pick up on this cell story.
