Counter-Terrorism and Security Bill

The hon. Gentleman is far more informed on these matters than I am, and I certainly would not argue with him about that. This is a similar approach, but it psychologically categorises the processes within that and shows how it can be dealt with. It is easier for the people operating these systems to be able to recognise particular behavioural patterns and to deal with them. This does do what the hon. Gentleman says, therefore, but it is important that this has already been designed and that security personnel are working with it. In order to meet the issues raised in clause 18, it is important that we have such a system in place, but the only way we can do that is by sharing best practice. That has already been done by Sussex police, and I commend that approach to the Minister and hope he takes lessons from the work that has already been done by Detective Sergeant Mike Redmond. We should all acknowledge the great work he has done.
