I seem to remember that a bin Laden originally appeared, which got a news attention, in which he took credit for the 9/11 attacks. That tape got a lot of media attention and, in it, he said that he never expected the WTC to actually come down, so the attacks were even more damaging than they thought it would be.
But, then I believed it was eventually proven to be a forgery. Of course, the media didn't give that anywhere near the attention they gave to its discovery.
Does anyone else remember anything like this? And if so, is there any online documentation about it?
