LAPD underwent unprecedented reform in the wake of the riots. It’s certainly not a perfect department, but it is exponentially better than it was in 1992. You are making the opposite point you think you are. The riots and DoJ consent decrees are literally the _only_ tactics that have succeeded in the past.
The failure after the riots was that we didn’t treat it as a national problem and undertake systemic reform of our policing systems from root to stem.
