I agree that the best way of dealing with these people who pose a threat is to prosecute them and lock them up. That view has been shared with the assistant commissioner with responsibility for counter-terrorism. Indeed the independent reviewer of terrorism legislation, David Anderson, also made that point. On the question about intercept as evidence, that issue has been looked at on a number of occasions over the years. Most recently, it was considered by a cross-party Privy Council group, which reported some months ago and made it absolutely clear that, in the current situation, it was not appropriate to change the arrangements such that intercept should be used as evidence.
