...extract the operating system code and do a forensic analysis to see if the cheater language is or was written into the software...
Not really possible. But what would work is taking a few precincts and running them through the same SW and then handcounting the same ballots. Since they are not doing that (or doing a bogus unsupervised hand count in GA) we can safely say the fix is in. Nobody is interested in finding out, except Trump and a few tens of millions of followers and we don't count.
That’s what I told my wife. Do 100 hundred ballots. Have some people fill them out randomly. So many for Biden, so many for Trump, so many for Jo add in some senate and house seats. Hand read then all, tally and then run them through two or three different machines. If the numbers don’t match and especially if all the errors favor Biden you’ve won your case. This is assuming they haven’t reprogrammed the tabulators back to normal over the last two weeks. Were the machines secured or left vulnerable?
