You can see this story from the London Times as an example of commonsense policing or you can see this as a tacit recognition (even if only at a fairly trivial level) of an increasingly balkanized society. Take your pick:

Avon and Somerset Constabulary has begun to equip its female officers with a uniform issue hijab to wear when they enter a mosque. The £13 headscarves are embroidered with the West Country force’s name and logo, and come in two colours — black for police officers and blue for community support officers. A spokeswoman insisted that they were not intended purely to cater for Muslim cultural sensibilities but were multi-faith. “They are designed to be used in any place of worship and can be used to cover the head or the shoulders. For example, plain clothes officers could use them to cover their shoulders in a Catholic Church, or they can be used to cover the head in synagogues,” she said. The scarves were however developed in a joint project with the Aklima Initiative, which focuses on working Muslim women, and the Mosque Initiative – both Islamic groups.
