Independent journalists have been doing a great job of recording and live-streaming these events for some time.  It is clear, when free speech is allowed and channels like Youtube (Google) do not censor those feeds, that it has been the Leftist extremists who see no reason to limit violence and commit actual assaults, including attempted murders.  Yes, there was a very negative act of murder (per charges) by a right-wing extremist in Charlottesville, but that clearly was the exception in these events.  Finally, the hate-based Left, such as the "antifa" movement are being exposed for their ancient Stalinist belief.
