Scientific data points to government-made anthrax - The Frederick News-Post : Crime And Justice
FBI documents released to the public in 2011 contain strong evidence 
that the anthrax spores used in the letter attacks of 2001 had been 
prepared previously for U.S. biodefense purposes. We have recently 
compiled and analyzed the documents, which contain some 10,000 pages of 
scientific data, in the “Journal of Bioterrorism & Biodefense.”*
