Stop what you're doing right now. Go check FactCheck.org, Reuters, NPR, AP News, Washington Post, or any other fact-checker. EVERYTHING IN THIS FILM IS FALSE!!!
GPS is not pinpoint accurate (anyone who has used Google Maps and seen their icon jump from block to block knows this). In court, it can only be used to identify you as being in a particular area. Ballot drop boxes are intentionally placed in high-traffic areas, like libraries, malls, or schools. In my case, it was across the street from the grocery store I walk to, right next to the library, perpendicular to a major road.
Most people interviewed in this film refused to cooperate with independent fact-checkers. One that did attempted to show the GPS technique, only to be informed that his locations did not match up.
At no point does this film show anything illegal. That begs the question: if the makers really did have proof of fraud, why didn't they submit it to the FBI, or even local authorities? (This is how 4 illegal votes for Trump were uncovered in the Florida villages)
Seems kinda selfish that the makers would prioritize making money for themselves over bringing people to justice.
