Clippy,
Please prove that the "chubby Osama" video is a fake. Many(maybe most) of us have seen it from start to end and looked at the famous freeze frames "proving" that it's not the same Osama. We've also read the technical explanation as to how it happened. Meh, I find it quite convincing that this is just compression (to use a term that I'm not sure is technically correct - but you know what I mean).
So, it's up to you. I can claim that GWB looks too skinny on the innaugural address video from January of 2005, and just keep claiming it as many times as someone drags out witnesses who were there, and video experts to refute it. That won't make it true. Why? Well, because my only evidence is the same as yours (collectively - all of you who still drag out this stupid theory)... "It seems to me...."
Somehow, solely your own incredulity doesn't weigh up much against the evidence that the three top members of the organization have admitted that they did it. They're proud of it, and they want you guys to stop trying to give their glory away to their (and your) hated enemies, Bush-Cheney.
So, you go ahead and bring out some evidence. That's your job. Just hand-waving away all other evidence isn't even on the job description! Our job is not to prove to you that any actual evidence is real. If we've seen something that we have reason to doubt, we'll debunk it (ask Ace Baker)... when you make outrageous claims based on "it seems to me..." then you either prove them or you prepare to be roasted over the open fire of logic. In the evidence game, in short, YOU LOSE.
