In October 2001 we knew exactly (home address) where Osama bin Laden was, and were monitoring all his communications. He could not leave until late Spring 2002, he was cut off from the outside world except via means we were monitoring. The decision was made that it was more important for the career of George W. Bush that we be seen acting fast than we should act intelligently. It was deemed necessary to sacrifice victory for the political advantage of the American Conservative Movement. So we jumped both feet into the mud puddle and splashed Al Queada out in every direction with no blocking forces present to catch them. The American lunatic right wing created Al Queada, and it has through it's blatant incompetence and greed preserved Al Queada. It still does. America's leaders desire political power rather than strategic victory. Which is why we are such a good target for bin Laden.
