Consider: London (A Clockwork Orange, Anthony Burgess)
Feral youths getting high and murdering people at night is of course something that is locally familiar to you. But the idea that a law enforcement system exists that would actually punish said youths, even if they were privileged, makes this worth keeping on your lists. But remember that just as such incidents in your own country do not have the influencer clout to become world news, law enforcement available to privileged citizens in this world would probably behave very differently when the people being attacked by drug-crazed gangs are immigrants. You already know how to stay indoors and out of sight: just find a neighborhood with no history of droog activity. Move if you like: it might turn out okay.
