I dunno, I think maybe that is a big part of why these countries are so safe? It is a form of meritocratic classism if you will. You are expected to be a certain kind of (law-abiding among other things) person. If you behave like you might not be the kind of person you get an implicit "social credit" downgrade and are treated like crap end to end. Sure, they might be "overreacting" all things considered, but in the US on the other hand there are examples of clearly dangerous people being catch and released because rights and dignity, until they actually murdered someone. There's a tradeoff, but the Japanese approach appears to be closer to the optimal point.
