I've lived next to the equivalent of the favelas in the US. For reasons that didn't make sense at first, the crime didn't spill over. Just 2 blocks away. But that's capitol cities for you; the police take care of the streets the state senators hang out at, and every homeless guy and criminal very quickly figures out which streets are a no-go for them.
But likewise, you'll have parts of Brazil that are just as safe as Norway, and parts of Norway that'd scare a Brazilian. Almost all countries are like that, just that the ratio of safe to unsafe areas vary.
