As an erstwhile retailer: sometimes "diversion" occurs. Tiffany goes to a factory in Florence, says, "Make us 10,000 of these bracelets." The factory does but also produces an extra 1,000, and sells them out the backdoor into the market. Imagine if a ballot print shop did that...

And the extra ballots go on to a boiler room somewhere, where people fill them in with voters' signatures and Biden votes.

Then they get loaded onto a freight truck, to be trucked hundreds of miles into other states....

And taken to a USPS facility to be reintegrated into the postal system and delivered to a vote counting operation.

Would that be wrong? And what would it look like to the observing public?
