The search for bin Laden

The Washington Post reports:

Frustrated by repeated dead ends in the search for Osama bin Laden, U.S. and Pakistani officials said they are questioning long-held assumptions about their strategy and are shifting tactics to intensify the use of the unmanned but lethal Predator drone spy plane in the mountains of western Pakistan.

The article provides another clue to what the issue could be:

There has been no confirmed trace of bin Laden since he narrowly escaped from the CIA and the U.S. military after the battle near Tora Bora, Afghanistan, in December 2001, according to U.S., Pakistani and European officials.

If that is true (a big if), and since bin Laden's video and audio tapes since Tora Bora were all of the kind that could be faked (see here and here), there is the open possibility bin Laden died in Tora Bora.

Last May, Baitullah Mehsud, a top Taliban commander, said bin Laden was dead.
