The National Academy of Sciences has reviewed the FBI’s forensic claims regarding Bruce Ivins and the Anthrax mailing investigation, and has politely called bullsh%$ on this:

The National Academy of Sciences is just out with a 190-page review [1] of the forensic science behind the FBI’s investigation of the 2001 anthrax letter attacks. The takeaway: Some of the evidence cited to identify Army microbiologist Bruce E. Ivins as the perpetrator isn’t as conclusive as the FBI has claimed.

In particular, the panel of experts said it “did not definitively demonstrate” that the source of the anthrax was spores taken from a flask controlled by Ivins, a microbiologist who did vaccine research at the U.S. Army Institute for Medical Research of Infection Diseases in Maryland. Nor did scientific data generated for the FBI “rule out other sources” for the anthrax, the panel’s report says.

Considering the record on the investigation, the you can review their tactics to the prior “person of interest” in this situation (Stephen Hatfill, who was exonerated and received a cash settlement) and be rather surprised that he didn’t top himself as well.
