Be submissive to good, unbending to evil, gentle in generosity, untiring in love, just in all things.~ St. Columban, Irish missionary, 6th century.
If everyone sought to be good, there would be no or certainly less of a need for police, prosecutors, criminal lawyers or criminal court. Unfortunately, human nature being what it is and as long as there is civilized society, there will be the need for a criminal justice system.
