Did the FBI close the anthrax case too quickly?

Additional Forensic Investigation of 2001 Anthrax Attacks

The major implication of this study, as the authors note, is “that the evidentiary spore material was not diverted directly from RMR-1029.”1 This fact means that if the anthrax spores used in the attack were taken from RMR-1029, their preparation would have required extra steps prior to mailing. That type of purification would have required specialized machinery and likely would have left traces of the material on machinery. No such material was found, though, and in a recently settled civil case in Florida, the U.S. Department of Justice acknowledged that the specialized machinery was not available at USAMRIID.
