The criminal justice system is a group of institutions that work together to protect a society, prevent and control crime, and maintain justice; enforce the laws regulated by the company. As the years have passed and the company has evolved; the same goes for the criminal justice system and its methods for fulfilling its role in society. This brief analysis will evaluate the main facts that have influenced the criminal justice system for decades and which have influenced the evolution that the justice system is undergoing in a changing society (Muraski, 2009). Among the changes in the system, we will discuss the effect the changes have had on citizens and how their perceptions have also evolved. In the criminal justice system three main agencies can be identified, they are; the police, the courts and the correctional institution. The responsibilities of the police include maintaining peace, catching criminals, fighting and preventing crime and social services. Once officers are involved and it is determined that a crime or any other infraction has been committed, the case will move to the jurisdiction of the courts. The justice system will then be responsible for adjudicating the matter and then the correctional system will impose whatever punishment or treatment the courts deem. Once correctional systems have received an inmate, the punishment phase will begin, whether it be imprisonment, probation, or community-based corrections. The ones mentioned above are the three union agencies that process a citizen who has committed a crime against state law, as you can see, the process is similar to that of an assembly line one might find in a factory. All agencies are linked together as one for the “stick” system to be successful. Works Cited Cole, G. F., & Smith, C. E. (2008).
