The Consensus Model or Systems Perspective of criminal justice argues that the organizations of a criminal justice system either do, or should, work cooperatively to produce justice, as opposed to competitively (See: Conflict Model).
Criminaljustice refers to the system used by government to maintain social control, enforce laws, and administer justice.
Criminaljustice is distinct from the field of criminology, which involves the study of crime as a social phenomena, causes of crime, criminal behavior, and other aspects of crime.
The pursuit of criminaljustice is, like all forms of "justice" or "fairness" or "process", essentially the pursuit of an ideal.
The conflict model (non-System perspective or system conflict theory) of criminaljustice argues that the organizations of a criminaljustice system either do, or should, work competitively to produce justice, as opposed to cooperatively (See: consensusmodel).
This school of thought is followed both by groups which argue that the conflict model is the reality of criminaljustice, but the consensusmodel is the ideal; and groups which argue that the conflict model is both the reality and the ideal.
The model argues that police desire to put criminals into prison whereas prison officials who are concerned about overcrowded facilities may desire to release criminals from prison.
