If they had a video of Trump staring into the camera declaring his intent to send a mob to stop the transfer of power and maintain the presidency by force, they still wouldn’t do shit.
They’ll fry a few low level players. Maybe arrange some kind of edict which prevents Trump from holding office, maybe. But the ruling class isn’t going to set a precedent where a member of the ruling class can be held accountable. Not if they can help it. God I want to be wrong.
