The Right Thing™️ means a great many different things to a great many different people. Law is a way of funneling the most functional of these things into rules that most can agree with and live by. This requires a sacrifice of living not by your own ideology, but by one best for the whole, in exchange for a safe and functional society.
When The Right Way™️ starts catering to the interests of a few, the society becomes less safe and functional for the majority of its occupants. Thus making compliance and participation in its rules a bum deal for the populous. We obey by choice to get safety and security. When people stop feeling like society is fulfilling it's end of the bargain, they revolt. So the question is, at what point do you feel like you're being fleeced?
In the grand scheme of ethics... Probably immediately. There's nothing about the police or the legal system that entitles them to moral superiority. They're just richer and have more time on their hands. Keep in mind the legal system is the same legal system that gave us citizens united, two calamitous wars in West Asia, and golden parachutes for rich criminals. They're just a system of exploitation that makes sure their favored corporations get to exploit everything and everyone while we're all too poor and hungry to fight back because they've made it sink or swim for us
