I don't think we will or need to see any of that. Rational people, and for the most part, due to many varieties of willingness to pursue such an endeavor, will accept, with mostly presentable facts, the outcome of the election.
Trump, even if vigilant, or feeling necessary to fight and say I'm remaining until the last second of power possible, to fight this, would still have to have support of the government entities to allow such a thing after the fact. The American citizen can show up to D.C armed to the hilt,any number, if the U.S. Military is put out to defend, the citizen loses. That scenario of Americans killing one another is just not possible today.
It's possible, not probable, regardless of Trump and his want to stay. His bark and bite are irrelevant and impartial to the reality of the outcome.
He is fanning the flames, as he see's fit, and the other side is doing the same. We all have no ability to do anything about any of it, except sit around and talk about it.
