Asked whether he would apologise for his comments, Mr Griffin told BBC2's Newsnight: "No, because the law is an ass. A law which says that when you see a building with smoke pouring out of it, you can't shout fire, you can't give a warning, is a bad law." West Yorkshire police has said it would investigate possible offences. But it is unclear on what grounds the police or Mr Blunkett could take action. Incitement to religious hatred is not a criminal offence.
