Look at the nose-width difference.
The following three images are all from the same 2004 video...he looks different in each one. Short/Med/Tall...and as he gets 'taller' the nose becomes thinner, LOL!
What fascinates me is that who-ever it is, he's wearing the same clothes...the background appears to be the same as is the desk. But try as I might, I cannot find a live video of the 2004 tape.
IMO the 'bin laden' of the 2004 video was a FAKE. (How many body-doubles did Sadam Hussein have?)
