I am grateful to the right hon. Gentleman. He and I know that the police can operate only on information. Their success is not due to luck. They gain successes from little bits of information that may seem unimportant when they first come in. Fortunately, we have not been in the same position as the people of Northern Ireland, who know the importance of vigilance, but I hope that the people of this country will appreciate that it is important for them to cooperate with the police.
