It is clear that mayhem in more than 70 cities across the United States is not merely a spontaneous outburst of public anger about the terrible death of George Floyd, a black man who was killed at the hands (and knee) of a white Minneapolis police officer.

It is true that there have been many large, peaceful demonstrations of justified outrage. But in an ironic act of cynical cultural appropriation, to which many commentators turn a blind eye, these have been traduced by white, left-wing militants, many dressed in antifa black, who visit vandalism, beatings, and even death on innocent citizens and the police.
