What are the three main components of the U.S. criminal justice system?

• A. The three branches of government
• B. Law enforcement, the courts, and corrections, which work together to maintain law and order
• C. The executive, legislative, and judiciary
• D. Police, prosecutors, and defense attorneys

Answer: (B)

The three main components are law enforcement, the courts, and corrections, and they work together to maintain law and order by handling different parts of the process. Law enforcement investigates crimes, enforces laws, and makes arrests. The courts interpret laws, determine guilt or innocence, and impose sentences. Corrections carry out those sentences and supervise rehabilitation, probation, or parole. In practice, a case often starts with a police response and investigation, moves through the court with prosecutors, defense attorneys, and a judge or jury, and ends with the corrections system implementing the punishment and any programs to reduce recidivism. This tripartite structure best describes how the criminal justice system operates, as opposed to options that cite branches of government or just specific roles within the system.
