Places where the cops patrol in pairs after dark, where they know they're not welcome. I can think of several within 10 minutes drive of where I live. Some are black, some are Hispanic, none are Muslim.

But the police no-go Muslim zones is one of those myths perpetuated because it justifies a particularly ugly policy, or some "evidence" of the barbarity of the Other which demands our strict control. It has the additional advantage of not being immediately verifiable or debunkable since it is conveniently an ocean away.

Its not unlike the "death panels" being set up by Obamacare. Or the concentration camps they're going to throw all the gun owners into once the jack-booted Liberals take over.
