what I think they believed, was that they would not be able to identify the hijackers
Therefore it would be tough for us to identify who did the attack,
and be limited on who we could attack

Poor taliban underestimates the brains and commitment of the U.S.
and right now the deceased Usama is saying, "My Bad"
