I agree. I also speculate that just prior to the 9/11 attacks, the organization became aware that Atta had developed a strong grudge against someone associated with the Florida tabloid due to some precieved personal affront which was becoming an obsession for Atta. The affront may have had to do with a precieved slight on the part of a woman. I further speculate that, wishing to calm down Atta and/or to cement his resolve for the coming mission, the organization tossed Atta a sop by sending the letter to the American Media Corporation. Atta may have been present while the letter was prepared, or Atta may have posted the letter himself. Because this letter was not a priority to the organization, they did not use their best Anthrax for this letter. I don't think the FBI has released the text of the letter that went to the Florida tabloid, if it's even survived, but I'd bet the text and tone of that letter was different than the other letters.
