What is Criminal Justice? (Definition, Goals – Doing Justice, Controlling Crime, Preventing Crime)

What This Is

Criminal justice is the system of institutions and processes designed to enforce laws, maintain social order, and protect the rights of individuals. Its primary goals are to do justice, control crime, and prevent crime. The criminal justice system encompasses law enforcement, courts, and corrections.

Key Definitions / Models / Steps

• Due Process: The right to a fair trial, as guaranteed by the 5th and 14th Amendments to the US Constitution.
  • Example: In Gideon v. Wainwright (1963), the Supreme Court ruled that the right to an attorney is essential to a fair trial.
• Equal Protection: The principle that all individuals must be treated equally under the law, as guaranteed by the 14th Amendment.
  • Example: In Brown v. Board of Education (1954), the Supreme Court held that segregation in public schools is unconstitutional.
• Punishment: The consequence for committing a crime, which can include fines, imprisonment, or other penalties.
  • Example: In Harmelin v. Michigan (1991), the Supreme Court ruled that a life sentence without parole for a non-violent crime is unconstitutional.
• Rehabilitation: The process of helping offenders change their behavior and become productive members of society.
  • Example: In Miller v. Alabama (2012), the Supreme Court held that mandatory life sentences for juveniles are unconstitutional.
• Restorative Justice: An approach that focuses on repairing the harm caused by a crime, rather than punishing the offender.
  • Example: In Victim Offender Mediation (1990s), community-based programs allowed victims and offenders to meet and discuss the crime.
• The Crime Triangle: A model that explains the relationship between crime, victim, and offender.
  • Example: In Routine Activities Theory (1979), Lawrence Cohen and Marcus Felson proposed that crime occurs when a motivated offender encounters a suitable target.
• The Rational Choice Model: A theory that explains why offenders choose to commit crimes.
  • Example: In Rational Choice Theory (1980s), Gary Becker proposed that offenders weigh the costs and benefits of committing a crime.
• The Broken Windows Theory: A model that explains how minor crimes can lead to more serious crimes.
  • Example: In Broken Windows Policing (1982), James Q. Wilson and George L. Kelling proposed that police should focus on minor crimes to prevent more serious ones.
• The Community Policing Model: A approach that emphasizes building relationships between law enforcement and the community.
  • Example: In Community Policing (1990s), police departments began to focus on building trust and partnerships with the community.
• The Justice System Model: A framework that explains the different stages of the justice system.
  • Example: In The Justice System Model (1980s), criminologists proposed a framework that includes law enforcement, courts, and corrections.

Practical Application

In a realistic scenario, a police officer responding to a domestic violence call must balance the need to protect the victim with the need to ensure the offender's rights are respected. The officer must follow procedures to ensure the victim's safety, such as separating the parties and providing medical attention if necessary. The officer must also follow procedures to ensure the offender's rights are respected, such as reading the Miranda rights and providing an opportunity for the offender to speak with an attorney.

In court, a prosecutor must present evidence to prove the offender's guilt beyond a reasonable doubt. The prosecutor must also ensure that the offender's rights are respected, such as providing an opportunity for the offender to testify and present evidence. The judge must ensure that the trial is fair and that the offender's rights are respected, such as providing an opportunity for the offender to appeal.

Common Misunderstandings

• Misunderstanding: The criminal justice system is only concerned with punishing offenders.
  • Correction: The criminal justice system has multiple goals, including doing justice, controlling crime, and preventing crime.
• Misunderstanding: The police have the right to search anyone they want.

• Misunderstanding: The courts only consider the facts of a case.
  • Correction: The courts must also consider the law and the offender's rights, as guaranteed by the 5th and 14th Amendments.
• Misunderstanding: Rehabilitation is only for non-violent offenders.
