The foundations of how the criminal justice system is laid today, despite some major adjustments and changes along the way, still include vestiges of the school classic of criminology. People having free will, an attraction to crime, the ability to possibly reduce crime out of fear of reprimand or punishment, and knowing that crime must be serious, certain and rapid, the components of classical school of criminology are very useful and powerful. (Siegel, 2011, p. 9, paragraph 1). Specific deterrence is an excellent tool to use to show the criminal how severe a punishment can be (Siegel, 2011, p. 100, para. 1). General deterrence, on the other hand, shows all criminals a perception of the real threat of punishment (Siegel, 2011, p. 95, para. 10). Criminals attract criminals, and criminals also have access to the media, so they have plenty of opportunities to see the results and hear about the consequences of being arrested for crimes. However, the legal and judicial systems have a moral responsibility to ensure that criminals know that their crimes are punished severely. Society at large, a person's parents or guardians, and the media must ensure that the penalties for particular crimes are well known to prevent their respective audiences from making the same mistakes. Rational choice theory is an excellent method to use, provided you provide the criminal with enough evidence to understand that the crime simply has no effect.
