It looks child-like to me - all caps and written very big. Why didn't they print the address on a computer, so the handwriting could not be traced?

Nothing about it seems sophisticated. Contrast that with the ability to produce anthrax spores. This seems to me like the hijackings--a couple of guys in the "know" and a bunch of dupes to carry out the plan. They probably handled this stuff without knowing what it was. Expect some more of these terrorists to turn up dead.

You said, "It looks child-like to me - all caps and written very big." Could the terrorists (or unknown suspects) have had a child address these envelopes prior to inserting the anthrax? Remember, there are a group of kids that supposedly had prior knowledge to the events of 9-11 in the NYC area.
