Trump supporters weren't the ones being executed fool. They were the executioners. Nearly all of the arrests for violent attacks, arson and looting were of right wing thugs and terrorists, anarchists looking to stir up shit, and gangs of professional looters.
No members of BLM were arrested. No anti-fa. Just Proud Boys, Boogloo Boys, and 4Chan looters.
But you keep believing Trump's lies about the demonstrations. Trump WANTED those demonstrations to turn violent. He was using them for his re-election.
