"Thousands gathered Sunday in response to a planned anti-Marxism protest that was canceled amid concerns demonstrators might be attacked. The counter-demonstration was largely peaceful for several hours until the antifa, or anti-fascists, overran police barricades around the protest area. The violence was swift but brief, and among those targeted was Joey Gibson, leader of the right-wing organization Patriot Prayer that had called off a demonstration a day earlier in San Francisco."

"Berkeley Police Chief Andrew Greenwood said officers were told not to actively confront the anarchists. He applauded officers’ restraint, saying it forestalled greater violence. Six people suffered injuries, including two who were hospitalized, and one officer was injured while making an arrest and several others were hit with paint."

"There were 13 arrests on various charges including, assault with a deadly weapon."

“The potential use of force became very problematic” given the thousands of peaceful protesters in the park, Greenwood said. Once anarchists arrived, it was clear there would not be dueling protests between left and right so he ordered his officers out of the park and allowed the anarchists to march in."
