The "anthrax letter" was mailed by the DAUGHTER of the Kenyan recipient. It was MOLD or MILDEW on cloth. You seem surprised that a Third World country botches a medical test? You think a key aspect of Al Queda grand strategy is mailing anthrax from Atlanta to obscure Kenyan doctors?
Can you just admit you were wrong and move on? That's the thing about conspiracy theorists..they NEVER have to admit they are wrong. Anything supporting them is valid evidence. Anything undercutting their position is fabricated as part of the conspiracy.
I admit that it is more likely than not that the Nairobi letter contained no anthrax. But I do not believe it is impossible.
Among other things, one can certainly imagine a reason why the Islamofascists would have sent anthrax to a doctor in Nairobi. 9/11 happened the day before 9/12, when the defendants were scheduled to be sentenced in federal court in Lower Manhattan for the bombings of our embassies in Tanzania and Kenya -- Nairobi, Kenya.
Anyway, you're throwing cold water not only on my reminding people of the Nairobi letter (which I quite deliberately refrained from calling an "anthrax letter,") but also on any possible connection between these four guys in CT and the anthrax. On that at least, your air of certainty strikes me as inappropriate.
