Which of the following refers to the three main institutions of the criminal justice system?

The three main institutions of the criminal justice system are indeed the Police, Courts, and Corrections. Each of these components plays a vital role in the operation of the criminal justice system.

The Police are responsible for enforcing laws, preventing crime, and apprehending offenders. They are often the first point of contact in the criminal justice process.

The Courts are the judicial entities that interpret the law and administer justice. They handle the prosecution of criminal cases and ensure that due process is followed. Judges, juries, and various court personnel are involved in these proceedings.

Corrections refer to the various methods used to oversee individuals who have been convicted of crimes. This includes prisons, jails, probation, and parole systems. The goal of corrections is not only to punish but also to rehabilitate offenders and reintegrate them into society.

This framework helps ensure that the criminal justice system functions effectively, with each institution working together to uphold laws and maintain public safety. The other choices do not accurately reflect the primary institutions involved, encompassing various roles that are part of or supportive to the criminal justice process but not its foundational structures.
