Criminal justice is the system of practices and institutions of governments directed at upholding social control, deterring and mitigating crime, or sanctioning those who violate laws with criminal penalties and rehabilitation efforts. Those accused of crime have some protections against abuse of investigatory and prosecution powers. The criminal justice system is the set of agencies and processes established by governments to control crime and impose penalties on those who violate laws. How the criminal justice system works in each area depends on the jurisdiction that is in charge: city, county, state, federal or tribal government or military installation. Different jurisdictions have different laws, agencies, and ways of managing criminal justice processes.
