Don't let hardened criminals out early, says Justice Secretary Chris Grayling Mr Grayling is hoping to start a "rehabilitation revolution" which will lead to fewer prisoners returning to jail after release. The move should free up prison places that can be used to incarcerate those who have not "earned" early release. The Justice Secretary will also use sophisticated tagging technology to curtail the movement and freedom of some prisoners released early. He says: "What people don't particularly understand is why sentencing works in the way it does. If you get [sentenced for] 10 years, you're out after five automatically. It's not something that can be changed overnight, there are constraints on the system, there are constraints on prison places. Ultimately, I'm attracted by an option that doesn't simply automatically release you at a certain point, regardless of whether you've behaved well or not. The last Conservative election manifesto described the system of sentencing as "dishonest" and Mr Grayling says today that he wants to set out the "direction" of policy to tackle this problem. "These are not areas where you can deliver radical reforms overnight, you have to work in a direction," he says. My message would be that I get and understand concerns the public have over aspects of the system at the moment and I will take whatever steps I can to develop and reform the system in a way that makes that possible. One of the areas where possibly we've got increased scope in the future in monitoring offenders is GPS tagging where new technologies mean actually it's possible to watch an offender wherever they go. The Justice Secretary says this would toughen the regime for offenders, tighten curfews, and restrict their movements. "I get the frustration and I want the system to evolve and develop but you can't do everything overnight," he adds Mr Grayling was promoted in last autumn's reshuffle to replace Mr Clarke and his comments signal a further toughening of the Government's approach towards criminal justice. Although repeatedly stressing the need to improve the rehabilitation of prisoners, he also backs the greater use of prison for offenders. He says he will not cut prison places and insists that one reason that crime is falling is because more people have been in prison. Every police force will tell you when a serial burglar is behind bars their local burglary rate goes down. The Justice Secretary has proposed plans for a "payment by results system" to reward voluntary organisations and companies for mentoring and turning around the lives of former criminals. He has also established a review of the conditions in prisons and describes the ability of some inmates to watch Sky television as "crazy." Mr Grayling warns that it is a "challenge" to make prisons seem off-putting to criminals from "dysfunctional backgrounds." He says that "for some young people, prison is the first stable environment and so it is a challenge for us to make it an environment that they don't want to come back to." In his interview, the Justice Secretary urges the Liberal Democrats to stop attacking their Coalition partners. He describes a letter sent by Nick Clegg to his MPs calling for more attacks on the Conservatives as a "silly political document." He is also understood to believe that the Conservatives should consider pledging to leave the European Union but warns that supporting the UK Independence Party risks "gifting" the next election to Labour. Separately, he is drawing up Conservative plans to overhaul human rights laws, which "at the very least" will involve "curtailing" the reach of the European Court of Human Rights in Britain.
