I've ordered a copy in the naive hope it may contain something new.

This particular article cannot be informative. For one thing it misidentifies a "standard strain of anthrax used for testing" called Ames with the concept of "weapon".

You can certainly "weaponize" Ames, but you can also "weaponize" all other strains of anthrax.

And yes, the FBI has given up. The only folks still searching for the attackers are the USPS Postal Inspectors.
