Criminal justice system is a phrase used to express the interdependent components of the courts, police, and correctional facilities in the government. The term also describes the criminal justice agencies found within states in a federal government. As a whole the criminal justice system is thus made up of the three aforementioned interdependent components. Law-making has often been added by some as the forth criminal justice component, since all legitimate activity of the criminal justice system emanates from the law. The understanding of this is important because if the process of criminal justice is unfair, a portion of the unfairness will for sure stem from the criminal law. The substantive law aspect reflects the “what” of the statute, in that laws are established to define certain behaviour as crime, and thus give punishment to those who violate the law (Bohm & Walker, 2007). However in the recent times there have been calls for an overhaul of the criminal justice system. This stems from the diminishing public confidence in the system that has been accused of unfairness and inequity in performing its mandate. Hence a review of the criminal justice system is aimed at improving it to be fair, firm but compassionate, and colour-blind truly.
