The envelopes were "filled" in South Florida. In fact, at least one of them was mailed before the others were filled. That happened because the terrorist needed to have some more envelopes. Being your typical tight fisted young Arab he didn't want to waste money by buying a box at the grocery store (like an American), or waste money by buying too much postage.
So, he filled the envelope he had and when he got to the Boca Raton post office he mailed it in the letter drop in the lobby.
He bought several more embossed (postage affixed) envelopes at the post office, went home and filled them. These he deposited in street collection boxes.
Through normal mail processes these envelopes ended up in the Hamilton Twp. facility near Trenton NJ where they were postmarked.
Why would the terrorist wish to leave the country to pour powder in an envelope? Is the gravity different?
Why would the terrorist wish to leave the country to pour powder in an envelope? If you read my posts, I made that clear.
The terrorists did not pour powder in the envelope.
The experts who made the anthrax did,
then passed the envelopes back to the terrorists.
Are you saying that all the anthrax was mailed from Florida? That the AMI employees (Stevens, who died, and the elderly man who recovered) got anthrax through cross-contamination with those envelopes at the post office? That the anthrax mailed to New Jersey was then re-mailed to Daschle and others?
