Anthrax is not contagious, and not that easy to catch in the first place. Weaponizing it to the point where it can be easily spread has always been difficult. So my statement about spreading it through the city, insofar as any real danger is concerned, is admittedly overblown.

But like "dirty bombs," which (when using components that terrorists could handle without dying in their tracks) are not objectively that lethal, there is a powerful psychological effect that needs to be considered.

If a city got the idea that anthrax powder has been widely distributed, it would be a disaster on a panic basis, even if few people actually got sick.
