We know that our prison system is not working. We've been told over and over again, and last term by even the Prime Minister's own Chief Science Advisor, that prisons have failed. We've got the High Court telling the Crown that they are no longer to bring up the idea of deterrence, in drug sentencings at least, because all the evidence shows that deterrence does not, in fact, work; it is a myth. We have high recidivism rates. We have one of the highest per capita prison populations. We constantly get reports from the Ombudsmen and from others about abuse in our prisons. And we are not keeping down crime rates. We are not keeping victims safe. In fact, telling victims that we need more and more people in prison—we need to lift sentences of imprisonment—has now become callous, because we're not keeping them safe.
