The attached article explains that although the local authorities promised to install video at each dropbox, in many cases they never got around to doing that. In the midterms I would not be surprised if somehow any video coverage installed mysteriously gets sabotaged. And the mule drivers will tell them not to bring cell phones. (Or they can distribute cheap digit cameras or hack the tracking capabilities in cell planes).
I don't think we can ever prove the election was stolen in court. Some idiots actually voted for Biden. And there are powerful forces who would like to keep cheating every time. Make no mistake, it will take a determined effort to fix such problems in the midterms.
