it is strange to see the stills of this compared to the one released one year ago. I'm an artist and can calculate proportions of facial structure and noticed something odd very quickly. The OLD video showed a man with a wider  and deeper forehead- his eyebrows straight- This NEW tape shows a man with curved eyebrows.The eye placement to cheekbones is off and the nose isn't the same. Saddam had an entourage of look-alikes- who's to say Osama doesn't?
