From the August 20th story here, which also misses the growing polarization between antifa and BLM:
The atmosphere of the counter-protest was not as violent as these sentiments. Nor, with the exception of the small antifa group, was there the whiff of militarism that leaks from the alt-right. So President Trump was wrong to characterize the crowd as “anti-police agitators.” ...
In the park, the counter-protesters divided into two camps. The BLM protesters gathered on one side, the socialist groups on another. Eventually, the antifa and the police got to grips. The Police Department tweeted a request that people stop throwing “urine, bottles, and other harmful projectiles at our officers.” Twenty-seven people were arrested.
