My Lords, whenever there are reports of imams or anyone else preaching seditious material or any other kind of malicious doctrine, those reports are followed up. As the noble Baroness will know, the full force of the law is there to bear down upon them. The challenge is to find out where these people are and who they are. That is something that the community as a whole can play a part in highlighting. It cannot solely be for the police to do that. Indeed, it is important that communities should not feel that they are being spied upon all the time.
