Prison is the traditional and simple answer to a big problem. Yet, as last week's programme showed, because of overcrowding and under-staffing prison seldom encourages inmates ' to lead a good and useful life.' No one denies that for many of the 37,000 men behind bars there must be a better solution and now there are a few cautious experimental alternatives under way. In the second of two programmes JOHN PITMAN looks at some of these alternatives, including a hostel for men who have been in trouble most of their lives; an experiment in which boys - some with records of criminal violence -are working with disturbed children; a scheme sentencing convicted criminals to social work. In the studio JEREMY JAMES discusses other alternatives which are available and asks how many prisons could be closed if there were sufficient alternatives.
