Tucker is a little late to the audit party but hey, better late than never.
This is what happened:
The ballots scanned were identically marked in their entirety. The issue with double-ballot counting is that it circumstantially corroborates video-recorded evidence that appears to show Fulton County election workers running stacks of ballots through tabulators.
A video recording taken at State Farm Arena late election night showed election workers dragging out boxes of ballots from under a table after election observers were wrongfully sent home early. Then they ran stacks of ballots through tabulators multiple times for unknown reasons.
