This article from the Murky News is the closest thing I could find to an objective report:
Police announced 20 arrests and 11 injuries after fighting broke out between scores of people supporting or opposing President Trump who converged on a downtown park Saturday.
“The charges include arrests for assault with a deadly weapon and several other felony assaults,” police said in an announcement Saturday evening, adding that more arrests would likely be pursued after video and social media posts are reviewed.
Police had urging people to avoid the area around Martin Luther King Jr. Civic Center Park, citing a “large number of fights” and numerous fireworks thrown into the crowds at the protests. Police said also that there were numerous reports of pepper spray being used in the crowd.
“At this time, there appear to be no reports of damage to downtown businesses and no injuries to anyone not involved with the event,” the police department said in its announcement.
In addition to making at least 20 arrests, police seized a handful of cans of peppers spray, some knives, and dozens of sign and flag poles, skateboards, and other blunt objects.
Trump backers and members of the so-called alt-right movement were holding a “free speech” rally at the park, while opponents of the movement, calling themselves anti-fascists, headed to the same spot at about 10 a.m. Later, the demonstrators moved to the streets, where they eventually ended up on Shattuck Ave., blocking it from Kittredge Street to University Avenue.
It didn’t take long for hundreds people to gather in and around the park. Police in riot gear made at least 13 arrests and seized numerous prohibited items from the demonstrators by Saturday afternoon and indicated then that they anticipated more arrests would be made. Several people sustained injuries, but it was not clear how serious the injuries were.
“There continues to be a number of large fights, some property damage and numerous projectiles being thrown, including fireworks,” Berkeley police said in a statement issued at around 2 p.m. Saturday.
At several different times, loud explosions were heard in the crowd, immediately followed by fist fights in the crowd. Some people emerged holding their faces after the explosions.
BART closed its downtown station early Saturday afternoon, and did not indicate when it would reopen after
Berkeley police said Saturday afternoon they had reached out to Mutual Aid, a state program aimed to augment local resources that have become overwhelmed in emergency situations, for help.
Police had erected a light, neon-orange plastic barricade at the park between the two sides to separate the groups and were collecting sticks, flagpoles and other objects that protesters had brought, which were banned at the park in advance of the protest. The city had banned a number of weapons — or items that can be used as weapons — in the park on Saturday, including metal pipes, baseball or softball bats, lengths of lumber or wood of any size, poles, bricks, rocks, glass bottles, pepper spray and other objects.
Protesters on each side held signs in support of their cause. Anti-Trump demonstrators had signs saying “No! Pussy-Grabbing! No! Patriarchy! No! Fascist USA! Drive out Trump-Pence regime!” and “Fascisct scum your time is done.” Right-wing groups held Trump campaign signs and posters that read “Free speech,” among others. Photos circulated on social media showed some demonstrators making Nazi salutes.
First of all, the rally was not about Trump. There were Trump supporters there, but that was no Trump rally.
This was a Left versus Right streetfight. This time, the Right won.
The Left has had a monopoly on street violence since at least the Sixties. Republicans have never been big on street violence. The last incidents of rightwing street violence were southern Democrats opposing desegregation. You have to go back to the days of abolition to find organized GOP street violence.
Lately the Left has been ramping up street violence. It started with Occupy Wall Street. Then came Black Lives Matter. Now we have “The Resistance”. Gradually we have seen generally non-violent protests turn into riots. The Left now has a corps of radical activists they can turn out for action on short notice. Within that corps of radical activists is a hardcore group of violent extremists. Antifa is part of that hardcore group.
Meanwhile, the police have done nothing. They basically just stand back and watch as the leftwing mobs loot, burn, and destroy. They have allowed leftwing thugs to attack peaceful Trump supporters and to disrupt rightwing speakers.
Did they really think the Right would never fight back?
The people on the Right who are fighting back tend to be more radical than the average conservative. A lot of them are not very nice people. But the violent extremists on the Left are not very nice people either.
This new rightwing counteroffensive was easily predictable. I have to admit that after watching leftist thugs run wild for years it is enjoyable to see someone finally stand up to them.
But this is also disturbing. Civil wars don’t start overnight. They start small and then escalate. If law enforcement doesn’t retake control of our streets this is only gonna get worse.
