The FBI can identify all cell phones operating at that location around that time. The FBI can get the cell phone’s reported GPS location, accurate to 3 feet or less and which is logged by the cell services to be sold to data mining companies. If the people moving the fake ballots had a cell phone with battery installed, the FBI could go back to stored cell records and track the entire route, stops, and anyone who had a cell phone turned on and helped them along the route. Then they could track everyone involved with helping (with a cell phone turned on) and where they were before the event and after the event. The FBI could quickly and easily piece together the whole event. They have not and that shows that the FBI is deeply involved.
