It’s very simple! Cops patrol only poor neighborhoods and will spot (or outright invent) petty crimes. The petty crimes from the bourgeois neighborhood are outright ignored (if you have higher-classes friends who got stopped/released with cocaine, you know what i’m talking about) and cops certainly don’t invent things when it comes to rich people so all crimes such as “violence” or “insults” against a police officer simply don’t exist (on paper at least) in richer neighborhoods.

Also, it’s worth noting that richer people have better resources to cover their tracks, and that police/justice don’t care at all to investigate this kind of stuff which takes months and yields moderate results. It’s much easier to criminalize weed smokers or to lie about someone insulting you then resisting arrest. Also worth noting: cops like to fill their pockets and arresting people for drugs gives them access to free drugs, while arresting people under false pretenses of violence ensures them long-term benefits. Even if the person condemned can’t pay, cops usually have a nation-wide fund that will pay them any amount someone has been condemned to owe them.

Dismantle (or at least disarm) the criminal organization known as police and you’ll see suddenly things will get much better for everyone.
