That is a plausible argument, except that having a tag on your ankle is not a deprivation of liberty in quite the same way as being in prison. Being able to go on eating fast food, watching telly and doing all the other things that you might do at home is not quite as much of a deprivation, is it?
Moreover, we have heard this so often before. It is true that technology has moved on and the tags are of a rather different kind, thanks to the work that was referred to earlier, but when tags were first introduced we were told that the technology was such—these things were so secure—that no one would be able to evade their application or use, only to find that all that was wanting. My hon. Friend will therefore forgive me for a certain degree of scepticism—not cynicism. I am cynical about nothing. However, I am sceptical about this.
The second principle of criminal justice is to provide respite for those who have been victims of crime, and others who might be, by taking people off the streets. That is to put the victims and others out of harm’s way by removing the harm—literally taking the harm beyond their purview—which is what prison does. It may be that if these tags work perfectly—if these people are constrained in the way suggested by the Secretary of State and my hon. Friend—I suppose the victims may be protected anyway; but I suspect that people in my constituency and elsewhere who have been victims of some of the crimes concerned would say, “I want these people to be as far away from me as possible, and as far away as possible from my children, my home and my community. I do not want to know these people or see them daily, because they have done harm witnessed by those who live in my locality.”
The third principle of criminal justice is that once you have caught someone, convicted them and sentenced them, you might take steps to prevent them from committing crime again. Of course I understand that. There has been a long-standing debate between those on the retributionist side of the argument, like me, and those on the rehabilitationist side of the argument, like my hon. Friend the Member for Bromley and Chislehurst, who believe that crime is essentially an ill to be treated, and that the circumstances of the criminal—those were my hon. Friend’s words—are more important than the event of the crime.
