Also, on the matter of perceptions of looting, please watch this video showing black people asking (white) protesters to stop damaging property and looting
There's been lots of reports stating that white people are partly responsible for escalating the protests and inciting violence.
I've seen many videos of black protesters asking white people to tone down their anger/violence and protest peacefully.
There are also reports that some non-protesters are engaging in violent behaviour opportunistically (either for personal or political gain)
Excerpts from the "Many Claim Extremists Are Sparking Protest Violence. But Which Extremists?"
'“We have reason to believe that bad actors continue to infiltrate the rightful protests of George Floyd’s murder, which is why we are extending the curfew by one day,” Gov. Tim Walz of Minnesota tweeted on Sunday, after previously suggesting that white supremacists or people from outside the state fomented the unrest.
...“Groups of outside radicals and agitators are exploiting the situation to pursue their own separate, violent and extremist agenda,” Mr. Barr said. “The violence instigated and carried out by antifa and other similar groups in connection with the rioting is domestic terrorism and will be treated accordingly.”
...“We’re going to see a diversity of fringe malefactors,” said Brian Levin, the director of the Center for the Study of Hate and Extremism at California State University, San Bernardino. “We know for a fact there have been far-right agitators both online and at these rallies, as well as far-left.”
...Far-right adherents generated an avalanche of posts on social media in recent days suggesting the unrest was a sign that the collapse of the American system they have long awaited was at hand. These groups, known as “accelerationists,” attempt to promote any circumstances that might speed that goal.
The looting is being used as a tactic to gaslight legitimate demands.
Right-wing organisations are using it to spread division and to undermine the George Floyd protests.
Left-wing organisations (such as Antifa) are using it for their own agenda.
