Counter-protesters had permits for two parks close to Emancipation Park. And your account of peaceful "memorial supporters" is not supported by other, objective accounts of white supremacists chanting fascist and anti-Semitic slogans while carrying firearms (including semi-automatic rifles). Free expression is one thing, intimidation another. And many groups, including church groups and local residents, participated in the counter-protests. Again - violence is wrong. But protesting against racism and fascism is a moral and democratic duty.
