And the fact of the anthrax case itself had only been announced on Oct. 4, the day before the Troxler letter was postmarked.
Perhaps this is what "Skyway bridge-18 wheels" refers to?
"Oklahoma-Ryder Truck" - I assumed that was about John Doe #2 (and therefore ambiguous, since some people think he was an agent of the state, others a foreign collaborator).
My feeling is that the person who sent this letter thought that 9/11 was an inside job, and the moment that anthrax hit the news (October 4), they assumed it was more of the same. "Blow away this dust so you can see how the real thing flys"... I hate to admit it, but it does sound like a reference to the aerosol properties of the real anthrax, doesn't it? My head hurts!
Is this 'BMI' another 'French' (GM) connection?
:-(
