After having worked with computer programming since 1960, what I can tell you is this...
The software which created results can be expunged easily.
But the results the software created and were printed and distributed can never be destroyed toto.
All the lawyers need to do is prove that the tabulation results produced by Dominion systems is not possible. Such as processing X number of ballots by workers through the feeding machines in Y number of minutes. And 300% more ballots from precincts than registered voters. And all ballots with perfectly filled circles ONLY for Biden and nothing for any down line contests.
That one interests me in particular. Georgia law requires ballots to be sealed and preserved for 24 months. Those ballots should be subject to subpoena and inspection in an election contest.
