Even in the article, it states that they were able to reconstruct their movements. So, we have these 19 men, who have been traced to being on the planes...all with confirmed (despite the article, see earlier evidence) without much doubt, to be Al-Queda operatives... But, the deed was done by some "others"? The word for today, class, is Reaching....

And who was it, exactly, who suggested that there WAS such evidence?

"In addition, Mueller said, al-Hisawi's accounts in the UAE connect him to a man named Abdulrahman A.A. Al-Ghamdi, whom authorities now believe is Khalid Shaikh Mohammed, the alleged operational mastermind of the Sept. 11 attacks. Both al-Hisawi and Mohammed are at large and are among the most wanted al-Qaida figures remaining."
Not the Director of the FBI -surely?

If this were not so laughable, one would be tempted to cry.
