Anthrax and the Lone Gunman

The news today that a high-level government scientist killed himself just as the FBI was about to charge him with complicity in the post-9/11 anthrax attacks is highly disturbing in many ways. The fact that the source of the anthrax attacks that terrorized the nation for months during the aftermath of the 9/11 tragedy came not from some radical Islamic terrorists or Saddam Hussein, but from at top anthrax researcher working at the Army's bioweapons laboratory at Fort Detrick, Maryland, should raise some very serious questions.
First and foremost is the question as to why would he do such a thing and secondly who else was involved. It is not at all believable that a lone scientist could have pulled off such an attack and then covered it up without some major assistance. People should not be so gullible to buy into yet another “lone gunman” theory that allows the myriad conspirators to slink into the woodwork undetected.
As Glenn Greenwald notes in his must-read piece today, the anthrax attacks were too perfectly timed to support the neo-con drive to link Saddam Hussein to 9/11 and ABC News is aware of at least four high-level government sources who helped perpetuate the link by spreading thoroughly false information about a chemical agent used by Iraq that they said was present in the anthrax.
Who were those sources spreading the false anthrax/Iraq connection and what were their motives (as if it wasn’t obvious)? Greenwald spells it out thusly:

Surely the question of who generated those false Iraq-anthrax reports is one of the most significant and explosive stories of the last decade. The motive to fabricate reports of bentonite and a link to Saddam is glaring. Those fabrications played some significant role -- I'd argue a very major role -- in propagandizing the American public to perceive of Saddam as a threat, and further, propagandized the public to believe that our country was sufficiently threatened by foreign elements that a whole series of radical policies that the neoconservatives both within and outside of the Bush administration wanted to pursue -- including an attack an Iraq and a whole array of assaults on our basic constitutional framework -- were justified and even necessary in order to survive.

Are we going to be told that the now deceased scientist was the “lone gunman” who perpetrated the anthrax attack by himself with no assistance or coordination from others? And will the general public be so apathetic and complicit as to believe it without question?
We must have some answers, and if ABC News won’t provide them then some other news organization needs to step to the plate and deliver and soon. Because this house of cards isn’t likely to stand very much longer.
