I would be interested to know
whether the Iraqi/Iranian/Pakistani/al-Qaeda advocates on this thread
really believe this was a hoax by a third party
or
if not
why did they target Judith Miller?
Was it likely they even knew who she was or cared?
Two of the hoax letters were sent to NBC News and the New York Post, just like two of the real anthrax letters. Even more... they must have been addressed in the same way, since in each place the 2 letters were opened by the same person. The hoax letters were received before the real letters were discovered and publicized.
This is not believable as a coincidence.
So at least 2 of the hoax letters were sent as part of the same plot as the real anthrax letters.
