I think it is those Dominion machines that tilted the election. All that was needed was to identify the few critical counties where a slight difference would tilt the election and in those counties to add a slight weight to the vote for the Left--instead of 1.0 each vote would be 1.01. That would be enough to turn the election.
And in terms of the later protests on the sixth of January : The first ammendment is the right for peaceful protest. They did not break any law.
That was based on an event in England where someone was imprisoned for the "crime" of petitioning Parliament. See the Pamphlets of Daniel Defoe. So the right is meant for this particular kind of case.
