Compare and contrast the Charlottesville riot with the peaceful protest in Knoxville last night.  Both cities host the state's university,  and both cities were the scene of protests against Confederate statuary.  Charlottesville had fights,  injuries and a death.  Knoxville had none of those.  Perhaps its because the KPD set up a fence around the memorial in question,  and a barricade down the middle of the street,  keeping the pro-monument folks on one side and the counter-protesters on the other.  Charlottesville Police and Virginia State Police, OTOH, allowed, some might say forced, the two sides into contact,  with the predictable result.  Personally, I blame Gov McAwful for allowing the contact.
