A blind man can see that nose is not the same. 
Right after 9/11, Condi went on Meet the press and said there was undeniable evidence that OBL did it. She said a "white paper" would be out shortly, to show the world why we're justified in bombing Afghanistan.
A week later, Ari Fleischer said "we never said we'd be releasing that info". They never have.
To this day, 9/11 is NOT on Osama's rap sheet on the FBI list. Why? "We have no proof he was involved", they say.
The tape was released because many in the world media believed the US had conducted the attack to justify attacking Afghanistan. We had told India and UK 3 months BEFORE 911 we would be invading Afghan. in mid-Oct. they even printed it in their papers!!!!
Note that our own CIA, with the best technology in the world, confirmed that Osama tape was real. Look at those 2 noses. Now, if they WERE lying about that tape, what else are they lying about? WHY would they lie to us about Osama's guilt?
