I do not want to get into an extended dialogue. I understand exactly the point, but it is a fine balancing act and there is a real issue. If we are saying that one of the concerns is the extent to which these powers are exercised proportionately, given not only that it is extremely important for the entire community and entire society that these powers are exercised and that they exist but at the same time we are trying to avoid a situation in which there is a backlash, these matters need to be considered. I am sure that the Government have considered them and perhaps the Minister will give us an indication as to how they have tried to strike that balance, not in the circumstances where the powers have been used incorrectly or inappropriately but simply when this has happened.
I do not want to go back to the numbers question, but if for example we found that these powers were exercised quite widely because there was a real concern about people going overseas for terrorist purposes but necessarily because of those concerns there were a large number of false positives, the backlash in the communities concerned would be extremely great. It is just the same argument that arises about a very large number of stops and searches taking place—not that compensation arose there—simply to deter a small number of people.
