Like I’ve been saying, it’s about drugs. The rioters don’t want to get busted for drug dealing and other crimes, which crimes are associated with drug dealing (slavery, extortion, etc.). They want to rule over the residents in their neighborhoods without being effectively arrested or punished.
They're tired of getting busted for their illegal activities, and now they're squealing to defund and get rid of the police so that they can do whatever they please. Back to the law of the Jungle.
It actually gets pretty funny when these idiots get blowback and start calling for the cops.
