Sometimes incremental change is the best you can hope for. You think rioting and burning (and again I'll repeat, often BLACK OWNED) businesses is going to "change hearts and minds" to the point where these "right of center white people" agree that ripping police departments across the country down to the studs is a good idea?
I live in a mostly white, upper middle class suburb. For the last 2 years, across our entire area we have a large group of youths who roam around and steal cars. They are mostly black kids, there may be a couple that are white or latino. (I say kids, the ages range from 13 to 25 evidently). They steal cars from people's garages and driveways. They'll use garage door openers from unlocked cars in driveways, then enter the house through the garage if that door is open. They'll then take keys off hooks, etc. They joyride the cars, most of the time completely trash them, then ditch them. They've been caught a bunch of times, arrested, then let go within hours. The DA simply refuses to prosecute. They haven't caught all of them, but I know for a fact one 17 year old has been arrested SIX times for it and never charged. Recently, they escalated things. They dropped a cell phone on the lawn at a house they'd stolen a car from. When they went back for it, the people who lived in the house "confronted them" by yelling at them from their porch. How did the kids respond? By opening fire at these people. Luckily they were bad shots and missed them, though one shot only missed the lady by about a foot as she scrambled back inside. So...now it's attempted murder and they have pretty good images on the doorbell camera, but of course no arrests made on this one.
The reason I'm telling this anecdotal story is because I wonder how you think those people (affluent white folks), and people in their neighborhood and this entire town (hell this whole area) feel about the situation? Do they want less police authority? Do they feel these car thieves that don't even get charged with crimes and get to keep doing the same thing over and over are being "shafted"? When the ante is upped to now being shot at by this group while yelling at them from your front porch because they stole your car, are you feeling deep sympathy for how they'd be treated if they were to be caught and arrested?
These are likely some of the EXACT people you think need to have a huge change of heart (I say some because the area probably leans a bit to the left despite it being mostly white and somewhat affluent). Do you think seeing the same people get to do the same crimes over and over without ever being charged is going to bring sympathy to the cause from those that are needed to be "on board"?
