Police Department Organization: The local, state, and federal agencies are part of the criminal justice system that focuses on dealing with the problem of crime. The main components of the criminal justice system at all levels of government include police, courts, and corrections that deter or prevent criminal activities through arresting, trying and punishing criminals respectively.
