Consider for a moment what the optimal strategy would be to handle this vandalism and looting from the perspective of "Rich people." A) Capitulate to the demands of people using terror / destruction of property as leverage B) Utilize the vast resources available to you to end the source of the problem
I think your heart is in the right place in a very Robin Hood-esque kind of way but you're not grappling with reality if you think "give us justice and the looting will end" is going to play out favorably for the looters
Those vast resources that you mention (police and military) are at the very core of the conflict. Their use of force has only exacerbated the problem, because people spread videos of unjustifiable abuses (three cops brutalizing one prostrate individual in LA, a cop hitting protestors with his vehicle in NYC, a brigade of cops shooting law-abiding people on their own porch in Minneapolis, etc) that in turn draw more protestors to the fore.
Your A/B scenario is precisely the problem -- you equate the soothing of public anger with "capitulation" rather than "justice," and you make violence an imperative by arguing that the only strong approach is the brutal one.
Not to mention that you express a view that police brutality can "end the source of the problem." What is the source of the problem, if not police brutality itself? Were Americans violating curfews to demonstrate in the streets of major cities immediately prior to the murder of George Floyd?
