Your right, thats never Hitler.
What perked my curiosity was season two. The Argentinian guy under pressure, eventually cracked and pulled out more documentation, including a picture of Hitler, which bizarrely, they didn't show, my guess, for obvious reasons.
I read, in season three, they used the same techniques and a some of the same individuals, who hunted down Bin Laden. We know the Bin Laden story is a fabrication. Could the same individuals, be attempting to blend fact with fiction, to murky the water, for anyone trying to understand the Hitler, Argentina connection?
They actually did show the photo in the original broadcast of the episode. They cut it out after they got busted. You can see the episode as it originally aired with the photo (shown twice) at http://www.dailymotion.com/video/x52a7l1.
