The best people to help prisoners are prisoners themselves. Groups like the ones mentioned in this article will work if given the chance. Prisoner advocating groups from the inside can better prepare inmates than the placement situations awaiting them when they're paroled. Often times there is nothing--you're on your own. Other times, over staffed, under paid, or volunteers try to find employment and housing for the prisoners. The job's almost impossible without the cooperation of some sort of structure inside the prison.
Just about everyone would agree that the aim of incarceration is the protection of society and the rehabilitation of the prisoner. That's the goal, not hide the prisoner and forget about him.
Suicide is a cry for help.
