Anthrax attack still unsolved, five years later

At first glance, the list of potential suspects for this case must be vanishingly small. After all, how many people in the world know how to weaponize anthrax? But now the FBI is claiming that the spores weren’t as sophisticated as once believed:

In the August issue of Applied and Environmental Microbiology, FBI scientist Douglas Beecher sought to set the record straight. Anthrax spores mailed to politicians and journalists in September and October 2001, Beecher wrote, were not prepared using advanced techniques and additives to make them more lethal, contrary to ``a widely circulated misconception.''
The notion the anthrax spores were ``weaponized'' had fueled conjecture that only a government insider could have carried out the operation.
Beecher's article suggested a much wider universe of potential suspects -- who showed they could kill without highly refined spores.

Well. I feel so much better. Wake me when the investigation defrosts.
