One often hears of infamous prisoners who have been in training units for a year or two ahead of their planned release. We are familiar with the case of a particular prisoner who excited great interest in the media when he was released in recent years. Such cases tend to be seen in black and white. People ask why he or she – it is usually a "he", but it is a politically correct world so I will say "he or she"– should be released when he or she has committed such a heinous crime. The details of crimes are often retold in graphic language so that their horror is revealed to everybody once more. One may not have heard of the crime when it took place, or one's memory of it may have become dimmer as the years passed. The newspapers may remind the public of the details of the crime in graphic terms, with photographs, etc.
