I think a good portion of the violence can be squashed if people can see the fraud through the courts and Trump is not forced to make a "power" move
It might also help if it happens over time, get people used to the idea.
For example lets say one state gets thrown out/overturned then it has to be big news reported by everyone.
Will the MSM continue to lie when a judge says there is fraud?
The Dems and Deepstate will go scorched earth policy, they want unrest in the country. That is the next card to play for them, also the last one.
MSM will keep up with the propaganda, they can't and won't stop as they need to foment unrest by having the useful idiots believe they are being crossed and Trump is acting like a dictator and stealing the election
It will get ugly, very ugly I believe
