This is a fascinating (and long) newstory from the Washington Post on the still unsolved anthrax investigation. It is being suggested by scientists that the FBI has been unjustifiably holding on to an incorrect assumption, viz., that a single person is responsible. Here is an interesting paragraph: "Instead, suggested Spertzel and more than a dozen experts interviewed by The Washington Post in recent weeks, investigators might want to reexamine the possibility of state-sponsored
terrorism, or try to determine whether weaponized spores may have been stolen by the attacker from an existing, but secret, biodefense program or perhaps given to the attacker by an accomplice."
