In March 1973 guards went on strike at Walpole maximum security prison in the US state of Massachussetts, and the prisoners took over. For the next three months the inmates, organised in the National Prisoners Reform Association, ran daily life in the prison. They were helped by a group of outside observers, drawn from members of the community. Mike Lanchin has been hearing from the organiser of the observer teams, Rev. Ed Rodman, about his memories of this unique, but ultimately doomed, experiment in prison reform.
