re: I haven't seen 2000 Mules yet

It's pretty cut and dry. Their argument examines geolocation data farmed from people's phones and data mining techniques to correlate unique phone ID's to geofenced areas and times. From there they can backtrack the identity of the anonymized phone data by geofencing areas like ballot drop boxes and they found that repeat visitors were dumping large amounts of ballots. They have it all on tape because they also know the exact time of the visitors.
The cringiest part was having Charlie Kirk and PragerU have a powwow talking about the impact of this finding and blubbering as part of the film...
The question now remains, what will be done about it and will they make the dataset/report public for us to analyze?
