REMEMBER, EVERY POLITICAL ACTION SPARKS A POLITICAL REACTION: Violence by far-left protesters in Berkeley sparks alarm. “The clashes came despite widespread calls from activists and elected officials across the Bay Area for peaceful civil disobedience and underscore Berkeley’s growing reputation for violent reaction by the far left. Other protests earlier this year in the city turned ugly, with far-left and far-right forces fighting in the streets. Some in Berkeley worried that Sunday’s chaos, captured on video and quickly disseminated through social media, would provide unwanted ammunition to Trump and his supporters.”

Yes, that’s the big worry: That it might provide a right-wing talking point.
