The criminal justice system is made up of models and theories that often contradict each other. Of these models are the crime control model, the due process model, the consensus model, and the conflict model. This paper evaluates and defines these models, as well as the role of each entity in the criminal justice system within each model. Police, corrections, and the justice system all adhere to each model in some way and hastily in cases that require such a response. As described by Erik Luna in Models of Criminal Procedure, the following statement summarizes the above mentioned in the most appropriate way. The slippery slope becomes exceptionally slippery during times of intense public anxiety and perceived social danger. History teaches that grave threats to freedom often come in times of urgency, when constitutional rights seem too extravagant to bear (Luna, 1999). Historically, regardless of when these types of approaches were explicitly defined and named, they still existed in the different types of approaches used in the justice system by each entity. Models of Criminal Justice The Consensus Model The consensus model is based on the thought that people, as a society, will reach an agreed upon consensus regarding the appropriate criminal justice approach. “Those individuals whose actions deviate from established norms and values ​​are considered a threat to the well-being of society as a whole and must be sanctioned (punished)” (p. 5). Regarding the consensus reached by the majority, the realist approach on what is illegal and who should be punished; the assumption is that those who live in a coherent society can decide moral values ​​and norms of behavior.[sic] “Society passes laws to control a… medium of paper… related to their The objectives are intrinsically clear as over time the system has done nothing but show improvements. The system is based on trial and error and much is spent evaluating the methodology used to improve it further. These models are also monitored through community surveys and statistical information on crime in each element of the criminal justice system and have proven effective.
