No. Let's not forget that the primary targets were card carrying liberals. And let's not forget that the letters were written by someone very poorly portraying themselves as Islamic. A muslim, writing in english would not say "Allah is great," he would say "God is great," because "God" is the english word for Allah.
The evidence points very strongly to a far right luny. It's time for normal conservatives to come to grips with the fact that the far off the edge right is just as nutty and just as dangerous as the far off the edge left.
Otherwise we fall into the pit of using "negative evidence" to assert guilt. May I remind you that the New York Times, Los Angeles Times, Chicago Tribune and Washington Post were NOT ATTACKED! And the premier left-wing media institution in the US, National Public Radio, was likewise not attacked.
Does that mean they engaged in a conspiracy against the two major tabloid format publishers - the New York Post and AMI (National Enquirer)?
It does not. And the same goes for the idea that some right-wingnut did the job.
Yeah, sure, like the New York Post, or the Sun tabloid. The original target was the office of the 9/11 hijackers' landlord's office. The first target was chosen, for reasons still unknown, long before anybody but the hijackers themselves would have known about the connection. That fact alone is entirely dispositive of the source of the anthrax. That anybody could even entertain the idea that the anthrax threat campaign is not associated with the 9/11 attacks is a testimony to the almost limitless power of human stupidity.
