My Lords, research into alternatives to imprisonment has been going on for an extremely long time and will continue. Of course we accept that there are people in prison who should not be there. That is one reason why we look forward so much to the report of my noble friend Lord Bradley in January, which will deal with the issue of mental health and those in prison. We are working all the time to try to make sure that only those who need to be in prison are there, and to find alternatives for those who do not need to be there. The lesson for all outside is that people should not commit crime.
