I agree completely with you regarding “suspicious mail”. Someone saw our “For Internal Use Only” poster describing “suspicious mail” and thought “What a great idea!”.
I can guarantee you that if someone had dropped 10 of these packages with insufficient postage in a collection box, someone would have noticed. 10 or more letters, packages, etc and regulations require the Post Office to return them, not send them on.
The only picture I have seen with a sticker saying postage due on it was the package being sent to Biden and you know his crowd sure isn’t going to pay that 75 cents. $3.75 postage is only going to be enough for a 6 oz package anyway. Not an explosives expert, but that is an awfully light-weight bomb.
Odds are that none of the intended recipients would have been the one to open the package. Most of these people would have a mail room or an assistant to take care of the menial task of sorting their mail.
