My Lords, I had not intended to speak in this debate and will do so briefly. I have listened carefully to those who oppose my noble friend Lord Marks, and I am afraid that I am not convinced by them for two reasons. First, the cases that they cite are ones in which the judge would almost certainly have sent the person to prison anyway. When somebody carries a knife with serious intent and uses it, that is when people go to prison. We do not need the clause for that reason.
The other point has not been mentioned at all. The clause is supposed to be a deterrent, mainly for young people, to prevent them getting involved in carrying knives in the first place, which is a very laudable objective. However, let us remember the development of children’s brains. The majority of the development of children’s brains happens between birth and three years of age, but there is a boost during the teenage years. That is when risk taking comes in. If noble Lords consider that, they will realise that a deterrent such as this very small prison sentence—I quite agree with the noble and learned Lord, Lord Woolf, that it will do nothing but harm—will certainly not deter someone whose brain is telling them, “Now you can take risks, and you should”.
