"Also - seeing how Leahy claimed he was told his letter contained enough anthrax to "kill 100,000 people", wouldn't we have seen some whiff of powder or dust in that picture by picture story of the opening of the envelope?" There is a picture showing that.
These are the 4 pictures from the FBI website of the "Opening the Leahy letter", in order.

They are also in order as to the file names - photo1, photo2, photo3, photo4... It seems to me there is a photo missing at least between 3 and 4. Where is the picture you saw with the powder or dust showing, whether it's a cloud of it or some sprinkles on the desk?
Don't know if anyone has mentioned it before but the printing looks similar to the letters the serial killer dubbed "The Zodiac" sent to the SF Chronicle back in the late 60's/Early 70's.
Interesting.
