Final answer:
The stages of the criminal justice system include the police, courts, and corrections institutions. County government systems like the commission system and council-elected executive system are not part of the criminal justice system as they pertain to local government management.
Step-by-step explanation:
Which of the following is NOT a stage of the criminal justice system, as described by the text, Government in America? The criminal justice system typically consists of three main components: (1) the police, responsible for identifying and apprehending individuals believed to be criminals; (2) the courts, which determine the guilt or innocence of the accused and assign appropriate sentences; and (3) corrections institutions such as prisons, which implement the penalties decided by the courts.
Options such as county government systems like the commission system, council-elected executive system, mayor-council system, and council-administrator system are not stages of the criminal justice system. These systems relate to local government management and not directly to the adjudication of crime, which is the domain of the police, courts, and corrections.
