I am grateful for the Minister's assurance. I shall not go over our arguments for believing that beyond saying that many speakers in this mini-debate have referred to the difficulties in establishing the necessary evidence and the necessary mental element in this truncated procedure. I think of what the noble Lord, Lord Windlesham, said. That point was laboured effectively by my noble friend Lord Thomas of Gresford. For all those reasons, we are not content with leaving matters as they are.
Guidance is guidance.
The police have the job of working the scheme. It is their discretion and their authority that will be at stake. Indeed, it would be dangerous if the Home Secretary's non-statutory guidance could tie the hands of police forces. We think that the discretions are too wide and that the experiment is too wide. If the Government were to accept the proposed de-limitations, it would be helpful all round.
