The three agencies in criminal justice (in a consensus model, like in the United States) are the police, criminal courts, and correctional agencies. A case will go through the agencies in that order, starting with the police (which identifies crimes) and ending with the correctional agencies (once the agency reforms and reintroduces the convict to the public). The police identify and investigate crimes, the courts hold trials and sentence those found guilty of crimes, and the correctional agencies carry out the sentences that the courts set.
The importance of the different components within the criminal justice system is to have fairness, professionalism, integrity, and impartiality are expected of all criminal justice personnel at every stage of criminal case processing, and it is a special duty of the courts to ensure that these expectations are met.

Criminal justice classes study the systems and processes of criminal justice in their own nation. In the United States this means learning about the police, the courts, and the correctional agencies, and then learning how a criminal case would move through these agencies. Further classes may learn more about the specifics of criminal law, or the moral implications of different systems.
Enforcing the law and bringing those who do not to justice in the courts.

Criminal justice statistics are collections of data which pertain to criminal activity, and the actions of the criminal justice system. They are organized to compare crime rates over time or between places, and to evaluate the efficiency of criminal justice agencies. Two types of criminal justice statistics are collected in the Uniform Crime Report and the National Crime Victimization Survey.
Criminal Justice agencies can only provide the services that taxpayers are willing to pay for. Any public agency is happy to be allocated more money for their work.
Criminal justice is an ideal of a system that can properly deal with activity in violation of criminal law. Generally a class introducing criminal justice will walk you through the agencies which carry out criminal justice. The main 3 are the police (which enforce the law and investigate crimes), the criminal courts (which conduct fair trials and sentence those found guilty in accordance with the law) and the correctional agencies (which carry out those sentences humanely and aim to safely reintroduce convicts into society).
