At present, our justice system sentences are constructed in a way that allows for remorse, rehabilitation and evidence of consistent good behaviour. Partly to motivate prisoners to make progress and partly because our prisons are crammed full and we occasionally need to find ways to reduce numbers. Long term prisoners do not necessarily benefit from this, but the incentive to spend less time in prison at the end of their sentence applies across the board. Some prisoners will never earn such privileges, but many are rehabilitated and able to demonstrate their remaining sentence can be served in the community after they complete the required length. Serious offenders will usually go from prison to probation hostels, where they participate in a structured regime of further rehabilitation and education, as well as finding work.
