You've got that backwards. How about a little conclusive proof that he's actually alive - a picture holding a current newspaper or something?
He's been taking a dirt nap since Tora Bora.
True.
He probably met his 72 before the assault on Tora Bora. The Indian and Chinese press separately reported information that 2 of his guards had killed him and Omar and then died in the subsequent shootout. Each tape that has appeared since has been initially shown to be a fake (or one shot before the war) by our own government experts who have then shut up about it and subsequently spoken as if the tapes were real without actually saying that they are real. The press are the ones who have claimed government authentification and the government does not deny it-doesnt say anything.
That wouldn't prove anything. Would you like me to produce a picture of him holding a current newspaper, with your post clipped to it, while Elvis swings a hula hoop?

Dan Rather can probably provide that for you....
