I don’t think a race riot would happen today the way it did in the 60’s (I was in the middle of two of them,1966 and 1968, in Cleveland).
Back then, most people in the inner city did not have cars. The destruction was mainly in their neighborhoods, not the suburbs. Now everyone has a car.
Also, there were no cell phones back then, so it was much harder to organize things at a distance.
I would not be surprised, if such a riot happened today, it would look more in the nature of a “flash mob”, with hit-and-run attacks outside the inner city to sow fear and destabilize things.
I think the "flash mob" scenario is more likely this time.
Visualize a mob of a hundred or more showing up at the local mall or shopping strip, grabbing whatever looked nice, and leaving before the police can show up. With possibly designated rear elements with fire bombs to discourage pursuit.
Repeat over and over again until all the suburban shops go out of business.
