Tom Holsinger:

Richard,

The weaponized anthrax used on us was weaponized by a means unknown to the U.S. government, any of our allies, or the Russians (their chief biological warfare researcher defected and told us everything). it took the U.S. government, with all its resources, YEARS to reverse-engineer this process.

So you’re saying the Joker did it? Sounds like the Unabiochemist to me. Probably an ex-top guy like a Hatfill or Ivins (I presume), or maybe a Hatfilski or al-Ivins.

…

“the Russians did it”

The Russians did not do it, because they know that if we caught them, we would in theory have to respond with nuclear weapons. They didn’t do polonium here, you note.
