I mean this can be an easy fix if we had checks and balances. Each ballot has a barcode that works ONLY in that county. When the system scans the ballot it cannot be scanned again. If for some reason it needs to be scanned when it cannot, a supervisors can manually fix this I guess. But that's when you have 2 mfs sitting next to you watching. Or even better, each state invests in having hq cameras streaming over the machines. That way you don't even need someone watching next to you, if you're afraid of covid. Everyone in the world can participate as poll watchers. Also by live streaming it, even if the machine lies, we can go back and watch each ballot one by one.

I dunno I watch too much sci-fi and murder cases lol
