Saw a biochemist being quizzed on this subject on TV today. What constituted "weaponised" anthrax vs. normal anthrax came up in the interview. Thought you may be interested to hear the following...

Apparently anybody with a sample of the virus can grow anthrax and produce spores. Problem is, the spores produced in this manner clump together and are thus relatively heavy. They are no good for weapons because they lodge in the upper respiratory tract. (Sounds bad enough to me).

In order to get right into the lungs, the clumps of spores need to broken up by further processing. This is the "weaponisation" phase we've heard about.

So now you know. Blame the biochemists!
