Violent Crime Reduction Bill

Does my right hon. Friend accept that there is a culture whereby young people start to carry knives because they are concerned that other young people are carrying knives and that that perpetuates the problem? For example, one group of people is believed to carry knives. Consequently, a second group begins to carry them and then a third group starts carrying knives. As a result, the first group, whose members were perhaps not carrying them, also begins to do so. The culture is a self-sustaining spiral into despair.
