I am not going to post the videos because they are too disturbing.
Also, at this point, it's very difficult to determine exactly what happened and who is responsible.
However, it's clear the far-right extremist militia groups and white supremacist groups seem very intent on starting a second civil war.

We need to let local and state law enforcement to handle this stuff, not random, disorganized, far-right militia groups who appear to want to initiate violent conflict. For them, it's not about security from rioters, but it's about a politically-inspired armed conflict against all the protesters, whom they perceive as evil communists or something.
I think there is a strong possibility for violence after the election, and that is why it's very important that everyone works together to ensure a good election, a free and fair election where people can vote via mail-in ballot if they wish.
