Sure, no doubt the protests caused, and will continue to cause cases. But the protests were far more of a spontaneous thing....
Also think that this anti-racist "mob" also consisted of people who generally felt disenfranchised for a variety of reasons - low standard of living conditions, facing eviction or uncertain housing conditions, dismal employment prospects, about to lose health insurance, lost loved ones and friends, "stacked deck" in regards to justice, etc...echos of the existing inequalities in America. You could throw in some anti-Trump sentiment as well.
As always... there is also an apolitical criminal sector, who simply sees any civil unrest, riots etc, as just a good opportunity to burn, loot and cause all sorts of mayhem.
George Floyd's death and the other recent Police crimes....was a trigger....pulled on a already loaded gun.
