"On Sunday 14 June a delegation of people from the Consenting Adult Action Network (C.A.A.N.) went to West Midlands police headquarters in Birmingham to seek advice about just what material might be covered. Despite praising CAAN for its “mature and adult approach” to seeking advice on this matter, the police were unable to provide much help. They were unaware of imminent changes to the law in this area – despite the fact that West Midlands Police had contributed to the government consultation on this issue, and argued strongly for even tougher sentences than have been passed into law."
