On the other hand, governments often choose not to impose their will on Muslim-majority areas, allowing them considerable autonomy, including in some cases the sharia courts that Emerson mentioned. Alcohol and pork are effectively banned in these districts, polygamy and burqas are commonplace, police enter only warily and in force, and Muslims get away with offenses illegal for the rest of population.
The Rotherham, England, child sex scandal offers a powerful example. An official inquiry found that for 16 years, 1997–2013, a ring of Muslim men sexually exploited — through abduction, rape, gang rape, trafficking, prostitution, torture — at least 1,400 non-Muslim girls as young as 11. The police received voluminous complaints from the girls' parents but did nothing; they could have acted but chose not to.
