I'm not a minority and I grew up solidly upper middle-class. But even as a child, I knew that it was really dangerous to piss off the police.
Because the police were generally considered to just be the biggest and best armed gang. Because they acted that way.
Things have gotten much better in the ensuing 35-40 years here, but there are still serious, structural problems with police impunity -- especially if you're a minority[0][1]

Modern polling is what I based by contention on, and I don't think citing the most notorious counter-example (and reaching back before reforms to solve exactly the problem you allege) is much of a response.
Minority communities routinely poll in favour of INCREASED presence in their communities nowadays.
I'm pretty much with George Carlin (at least I'm pretty sure it was him) WRT the police: "It's not that I don't like the police, I just feel better when they're not around."
This is like the review site problem... people don't tend to walk around giving random anecdotes about good experiences with routine or common services.
But the polling is what I based my comment on. Even in minority communities, increased police presence polls significantly higher than decreased presence - and that's before proposing any reforms.
