An overview of the criminal justice system is important in that it lays the groundwork for future sociological studies of the function of criminal justice and deviance in society. The criminal justice system is comprised of the police, the courts, and the Constitution (including the Bill of Rights), and it's also an institutionalized way to control and mitigate the effects of deviance in society.
The criminal justice system can function and stay internally consistent because of the very simple idea of due process. Due process states that the courts, police, and the entire justice system must follow the laws laid out in the Bill of Rights.
EXAMPLE
If you’ve ever seen the television show “Cops,” you’ve probably seen the police read someone their rights--”If you don’t have an attorney, one will be appointed to you.” This is an example of due process.IN CONTEXT
Due process has other components, such as the requirement of a fair notice for your crimes. If you're being accused of a crime, part of due process is that you're fairly notified of exactly what you're being charged with. From that point, you can appear in front of a judge and have a hearing where you can state your case with counsel. This, too, is part of due process.
Lastly, you are entitled to a jury trial that objectively reviews the facts of your case. This is the final part of your due process. It's often cumbersome and expensive for the criminal justice system to go through with this final part of due process, the jury trial, so in an effort to save resources, what will often happen is a plea bargain, whereby the accused will plead guilty in exchange for a lesser sentence. This avoids the necessity of spending limited resources on a jury trial.
EXAMPLE
If you get arrested on a drunk driving charge, for example, the courts don't want you clogging up court time that should be devoted to a high profile murder case. Therefore the prosecutor will make you a plea bargain, which is an essential part of the justice system.The criminal justice system also punishes offenders. There are four functions of punishment that the criminal justice system is in place to do:
EXAMPLE
If you've read the book or seen the movie Clockwork Orange, you may recall how the offender was subjected to a very unique form of rehabilitation whereby he was brainwashed to be a better citizen. Lobotomy is another example. We don't do these things, but they illustrate the idea of societal protection through rehabilitation.Source: This work is adapted from Sophia author Zach Lamb.
