Senator Patrick Leahy expressed doubt about the FBI's case against now-dead suspect Dr. Bruce Ivins in hearings of the Senate Judiciary Committee yesterday.
That isn't really very newsworthy - lots of people doubt that the FBI's version is the full story.
The interesting part is that there will be independent review of the DNA analysis that lead to the alleged "fingerprinting" of the anthrax spores used in the attack, definitively linking them to anthrax samples at Ft. Detrick. I've thought since I first read about it that the DNA analysis was less certain than it had been portrayed, and it will be interesting to see what the National Academy of Sciences has to say about it.
It's still hard to imagine that Ivins would have killed himself if he were innocent, which at the very least suggests he was involved. But I tend to agree with the various commentators who suggest there's more to this story that we haven't heard yet.
