The Counter Protesters got their own permit?
Did they?
Or did they just show up to create violence?
Okay. Let's follow your line of thinking. Militia--men in body armor carrying rifles--and white nationalist groups with shields and bats, pepper spray, brass knuckles, masks, show up for a peaceful rally. Really? The counter protesters came ready for a rumble, too. Bats, pepper spray, the works. So both sides were armed and ready. Neither side is blameless here. But who organized this hate fest? Do you really think the degree to which these supremacists were armed indicates that they were hoping for a peaceful rally? Do you complain when the right shows up to counter protest a BLM rally or an anti-Trump rally? They have a right to put in their two cents worth, too, don't they? Or is it only if it's the Right that they have that right?
I think the cops dropped the ball here. Every single bat, shield and helmet and rifle should have been turned around and sent back to the car, on both sides. Come in clean or don't come. Peaceful rallies don't need that. You have two fists--use them if you need to defend yourself. Why did the cops let this turn into a huge gang fight and allow them to keep fighting? Were they scared? WHY?
