>>>The reason I am so sure they did not originate in New Jersey is the simple fact that there's absolutely no contamination found in any part of the postal facility "upstream" of the 010 operation where they were taken from a tray and then moved through the canceling operation.
I don't know what 'upstream' means but the box the letters were dropped in was removed.
Hamilton mail facility only just reopened about 6 months ago.
Hamilton also was not the only facility decontaminated.
All the mail goes through an annex before processing.
So I really don't understand your points still.
>>>What we have in New Jersey appears to be a mailer with a large stack of trays.
I can't comment on the rest of your note.
The point I made is very simple ~ each anthrax letter entered into the Hamilton facility for cancelation via a letter tray, not through collections.
