I just ran across this article which provides a history of bioweapons media spin and related government programs which could explain the FBI's inability to develop a strong case for the anthrax mailings:

MORE ANTHRAX SPIN FROM FBI AND NYT
...
William Broad seems to be the favorite of "investigators" (read FBI) as he has written numerous articles on the anthrax mystery laying out the current "thinking" of those investigators, even when they contradict earlier "leaks."
...
The Patrick interrogation is curious in itself. Patrick is the inventor (or at least holds five secret patents) on the process that developed the unique anthrax spore concentration of one trillion per gram, the same concentration found in the mailed anthrax. He is the former chief of product development of bio-weapons at Ft. Detrick. Patrick also is a consultant to Battelle Memorial Institute (BMI); a CIA connected government contractor. (See this writerís three-part series, "Anthrax, GOCOís and Killer Germs" which covers BMI in depth including its involvement in managing or co-managing four secret government labs including the armyís Dugway, Utah facility where the anthrax is weaponized.)
Patrick is also a close friend and colleague of Ken Alibek. Alibek is the Americanized name of the former number two man in the Soviet Unionís bioweapon program. He "defected" to the U.S. in 1992. At the request of the CIA, Alibek was "debriefed" by Patrick and was subsequently welcomed with open arms into the U.S. intelligence community. Alibek is also a former employee of BMI.
On December 21, 2001 the Columbus (Ohio) Dispatch newspaper reported that FBI Director Robert Meuller had assured Senator Mike DeWine of Ohio that no one with or formerly with Battelle is a suspect. BMI headquarters is in Columbus, Ohio.
The article goes on to describe a puzzling Defense Department program (Project Bachus?) in Nevada, "whose only logical purpose was to buttress the FBI theory of lone individual
perpetrators of chemical/biological events".
This was disclosed by Judith Miller just seven days before the 9/11 attacks and two weeks before the anthrax mailing to NBC. Another stated objective was to see if a "homemade lab" would have an identifiable signature. The founder is a CFR member and consultant to the CIA.
This project was apparently a failure and was a far cry from making weaponized anthrax.
ABC was also given permission to film the story, but they had never done anything with the film.
The article also describes the birth of the "Jefferson Project" where the CIA was tasked with developing a more deadly version of anthrax for testing vaccines, after Russia denied having ever developed such a strain. BMI was chosen to host the project which likely supplied the Dugway Proving Ground in Utah, and which then ultimately supplied Dr. Ivins at Fort Detrick. leveymg provides a detailed report on this here:
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=389x3778301#3783726Finally the article describes the CIA's Clear Vision project which focused on weapons systems that would deliver the germs. BMI was again chosen for this project, and it is speculated that this is related to "dirty bomb" development.
The article makes the point that the CIA is off limits to the FBI, so all they can do is find a lone suspect who matches their profile.
