What is The Purpose of Criminal Justice System?

The criminal justice system is a series of agencies and institutions that aim to protect the public, uphold the rule of law and punish offenders. The purpose of the criminal justice system is to ensure that criminals are punished, which will hopefully prevent them from committing further crimes. Also, the criminal justice system aims to rehabilitate offenders so they can reintegrate into society after serving their sentences.
Indeed, the police are responsible for investigating crimes and arresting offenders. They work closely with other agencies within the criminal justice system, such as courts, prisons, and probation services. Police officers may also be called upon to testify in court cases or give evidence at inquests into deaths that have occurred through violent means.
Courts are responsible for trying offenders and imposing sentences on them if they are found guilty by juries or magistrates sitting as judges over their cases. Magistrates sit alone when hearing most cases involving minor offenses such as littering or petty theft where there aren’t any witnesses present; however, some cases are heard by juries instead which consist of 12 members randomly selected from a wider pool of people who live locally around where these types of crimes occurred.”
