I'm no great fan of religionists proselytising in the street, but as the man said, I'd defend to the death their right to do so, however wacky their beliefs. And as a secularist, I'll complain till I'm blue in the face every time someone ascribes a religion to a geographical area, especially if that person is a state official. If the report is true, the police officer in question was behaving more like the enforcer of a sectarian neighbourhood protection racket than an officer of the law.

As he says: 'It is people who require protection, not religions, philosophies, institutions and other abstractions'. There's more on this over at the National Secular Society's website.
