I have heard that too, but have not seen any real clues into that story. But THIS one is made all the more believeable by the credibility of the people who are advancing it. This tip came from Pentagon sources. They know something. They want it examined and can't push it themselves. There is a bad wind here. Clinton/Reno/Freeh on THIS case, and the subsequent oddities and omissions in the actual investigation...to the stunning similarity between John Doe Number 2 and Mohammad Atta.
Is that your opinion, or have others made the link?
