I read about that one as well. We thought that a United Arab Emirates Prince was at the same location as where we thought Bin Laden was. We were almost 100% sure the prince was there, and were less certain that Bin Laden was there.
Tenet, Rummy, actually back the Clintonistas on this one. That was too risky a shot. The political blowback on being wrong, and killing the prince would have been a mess.
