My noble friend asked me a very interesting question, but I am not sure that I can answer it. I suppose that the short answer is that I am very conscious that this is a divisive issue and one that the police themselves have strong views on. They do not agree with each other—I have certainly heard a range of views within the police about its effectiveness or its blanket use being ineffective. I think that the answer is that the Government need to look at this issue very sensitively and be very aware of the distrust that it breeds within communities, particularly ethnic minority communities.
