Color me shocked, shocked to discover that we weren't really told the facts at the outset of this case. Five years, and this is the best they can do? My regard for the FBI is just shaken, I tell you:

WaPo - Five years after the anthrax attacks that killed five people, the FBI is now convinced that the lethal powder sent to the Senate was far less sophisticated than originally believed, widening the pool of possible suspects in a frustratingly slow investigation.
The finding, which resulted from countless scientific tests at numerous laboratories, appears to undermine the widely held belief that the attack was carried out by a government scientist or someone with access to a U.S. biodefense lab.
What was initially described as a near-military-grade biological weapon was ultimately found to have had a more ordinary pedigree, containing no additives and no signs of special processing to make the anthrax bacteria more deadly, law enforcement officials confirmed. In addition, the strain of anthrax used in the attacks has turned out to be more common than was initially believed, the officials said.

I love my pretty foil hat, and this case makes it seem especially shiny. Nothing I've read about this case makes any sense, except the suggestion that the thugs wanted to cow a bunch of pansy Democrats early on in the takeover. It worked, and like so many other crimes of the last six years, the guilty go unpunished.

I miss the rule of law, truly I do.

UPDATE: Alert reader Moe asks: how can we be sure they're not lying about this now? When the rage was all for Saddam's massive WMD programs, 'weapons grade' anthrax made a good meme. Perhaps now they'll discover this 'common' grade is straight from the butt of an Iranian goat.
