Are you crazy? On what basis do you make that claim? You should be over on the DU tinfoil hat forum.
Speaking of DU, you've been on this forum since 5.19.2004.
Since you asked so nicely, I'll explain why I don't think that man in the video was Berg. I've seen several pics of Berg. He is a tall, well built fair looking man. The man in the video had a smaller build, and was dark haired and more Arab looking. What's up with that Amish looking beard? There's too much wrong with this story, so it wouldn't surprise me if Berg was still alive.
I'm not the only one who has doubts, so why don't you look them up and tell them to go over to DU? I guarantee they won't be so polite.
