I can actually think of occasions when I looked at a magistrate and knew my client was inevitably going to get a custodial sentence, and I had to try to convince him of an alternative. One client would not come out of his cell and spent his time doing headstands. He could take any sentence doing it on his head. There were the odd occasions when one had to be counter-intuitive, particularly with magistrates, but my hon. Friend makes an important point.
The reality that I saw as a defence solicitor—not as a barrister, I have to say—was that all too often there were occasions when prison was avoided. A good plea of mitigation from an advocate—that the young person had the knife for his own protection, or was led up the wrong path by other people and so on—has led to individuals avoiding custodial sentences. Some may say that that should come within the exceptional circumstances category and that there is full discretion for magistrates. The new clause will make it resoundingly clear that there is a minimum mandatory sentence, and that it should only be in exceptional circumstances—coercion and other serious cases that do arise, but which are an exception—that magistrates can quite properly use their discretion. The new clause would ensure that it was very clear to victims, the public and offenders themselves that those who carry knives will go to prison. That has applied for some years to repeat drug offenders, repeat domestic burglars and repeat firearm carriers, and I understand that it is having an effect in relation to firearms offences in particular.
