I'm not sure what that's supposed to mean. You might think there is some nuance because the areas with risk of Islamic separatism are not _necessarily_ the same as the high-crime areas where the police cannot easily go. But in practice they definitely are. It's not a pleasant situation, but it's the situation. I can give more background if you are interested, but it is a well-studied problem with no solution in sight.
