So you are basically saying it doesn't work because people in the US just don't care if there is obvious bullshit going on. Okay, great (or not so great for the self-acclaimed forefront of democracy), but why should that change if the votes aren't anonymous anymore? Why should people suddenly start to care if the results actually make any basic sense and aren't obviously either manipulated or erroneous?

Any precinct reporting more votes than possible given the numbers of eligible voters is recounted. If the recounts can't manage to arrive at results that make any sense at all the entire precinct is ignored. Where's the problem?

As far as I know, the secret ballot is present in every state within the USA. Could you please cite your sources if you have different info (I've lived in 9 different states)?

Yep, there were several counties where they "found" extra ballots that they missed during the count in 2018 in the US.

It was across both parties in multiple states wherein the "found" votes were heavily favoring one party or the other (a few were well outside 3 standard deviations from the current votes, even in areas that were normally not heavily favoring one side).
