BUT... Every election cycle thousands of all democrat ballots (probably in alphabetical order) are “found” in the trunks of cars that were supposedly not previously counted. Wherever those votes were supposed to come from should be surveilled as well.
That act is well-known.
The voter registration list needs to be scrubbed before votes are counted. Then, when illegal ballots are found in closets, trunks, etc. those ballots are compared against the clean voter roll. The mailed ballot contains two envelopes, one inside the other, with voter information in the outer envelop and the voter’s vote in the sealed inner envelope.
In the past the democrats use same day registration, fraudulent homeless voter registrations, provisional ballots, to insert their fraudulent ballots.
Once a vote ballot is counted, it cannot be reversed as it is impossible to know which way it went once a fraudulent ballot registration is discovered. Once counted, there is no traceback to the fraudulent registration. Therefore, the ballot registrations must be examined before counting.
When comparing mail-in ballots received in election rooms with the cleaned voter registration roll, a process of voter verification, the ballots that do not match are set aside. This is where US Marshalls, their deputies and assistants need to be present because this is where democrats can attempt to intimidate those doing the verification match, and this is where democrats (think BLM/Antifa thugs) will attempt to take bags of ballots out of the verification rooms into other rooms to be counted out of view.
