I don’t know what everybody is worried about. In two, three generations at most, everyone will be completely used to it. Look at how well it’s worked out for Sweden:
The Swedish police has released a map of 55 areas where they publicly admit to having surrendered control to the criminal gangs. The report describes outright attacks on police officers trying to enter the areas, which is a step up from the previous problem with attacks on mailmen, fire trucks, ambulances and similar services; it used to be that fire trucks and ambulances had to wait for police escort to enter the areas, but now the police themselves need protection.
The no-go areas heavily coincides with the map of the 186 “exclusion areas” aka. crowded, predominantly muslim immigrant ghettos, where education is low, employment is lower, and the only local business thriving is that of the drug dealing (which takes place openly and continues to do brisk business.)
As the real law backs away, organized crime emerges to take its place. The police report notes that “a wider clientel [in the areas] are increasingly turning to the criminal authorities for justice” in a Godfather-like fashion. Unofficial courts and punishments are often meted out according to the codes of the home cultures of the dominant gangs. The report also point out that there are vehicle checkpoints at the borders of some of these areas. The bad news is that it’s not the police doing them; it’s the gangs securing their home turf against law enforcement and rival crime families.
