Just because a person is a Muslim does not mean he/she cannot commit a crime. Crimes are committed by human being irrespective of religion.
If Anjem C goes to prison then it needs to be understood that he will get special treatment; such as fresh clothes, cleanliness priorities, prayer preferences etc.
Everyone fills in the same form when it comes to dietary/prayer requirements. Unless you have evidence that Muslims get preferential treatment over the other people who have the same requirements then best not to go down that route.
