Fascinating. Roughly one in ten countries in the world have special religious police to enforce religious speech, action, and appearance. From the Pew Research Center:

As of 2012, at least 17 nations (9% worldwide) have police that enforce religious norms, according to a new Pew Research analysis of 2012 data. These actions are particularly common in the Middle East and North Africa, where roughly one-third of countries (35%) have police enforcing religious norms.
