Obviously, you comment in ignorance. The po po as you say worked with the event organizers to define a plan that would keep the nazis separate from the general public. They would still be able to make all their noise and visual regalia like the Nazi flags and KKK shit but the police could keep the two groups separate. The chief of Charleston police said that the organizers changed plans without notifying police and defeated their attempts to keep the peace.
So, no. It's the fault of the Nazis. They came to Charlottesville to bust heads and masturbate with each other later.
Video of chiefs comments saying exactly what I described is in the link below.

And so, you jump to the wrong conclusion yet again. As I said it's not in your DNA to be a thoughtful person one can talk to.
