Top Bin Laden Expert: Confession Fake

Was Osama Bin Laden responsible for 9/11?

The Bush Administration says yes, citing a grainy, badly-edited videotape that surfaced in December, 2001. In that tape, a fat guy who vaguely resembles Bin Laden chortles about the success of the 9/11 attacks. (In earlier interviews, Bin Laden had denied responsibility for 9/11, once even deploring the loss of civilian life in the attacks and calling them un-Islamic.)

Is the famous “confession video” genuine?
