Deterrence (legal)

Deterrence is the use of punishment as a threat to deter people from offending. Deterrence is often contrasted with retributivism, which holds that punishment is a necessary consequence of a crime and should be calculated based on the gravity of the wrong done.

The concept of deterrence has two key assumptions: the first is that specific punishments imposed on offenders will "deter" or prevent them from committing further crimes; the second is that fear of punishment will prevent others from committing similar crimes.[1]

Categories[edit]

Deterrence can be divided into three separate categories.

Specific deterrence focuses on the individual in question. The aim of these punishments is to discourage the criminal from future criminal acts by instilling an understanding of the consequences.

General or indirect deterrence focuses on general prevention of crime by making examples of specific deviants. The individual actor is not the focus of the attempt at behavioral change, but rather receives punishment in public view in order to deter other individuals from deviance in the future. The argument that deterrence, rather than retribution, is the main justification for punishment is a hallmark of the rational choice theory and can be traced to Cesare Beccaria whose well-known treatise On Crimes and Punishments (1764) condemned torture and the death penalty, and Jeremy Bentham who made two distinct attempts during his life to critique the death penalty.[2]

Incapacitation is considered by some to be a subset of specific deterrence. Incapacitation aims to prevent future crimes not by rehabilitating the individual but rather from taking away his ability to commit such acts. Under this theory, criminals are put in jail not so that they will learn the consequence of their actions but rather so that while they are there, they will be unable to engage in crime.

Not all crime deterrence comes from a criminal justice system. Controversial academic Gary Kleck concludes evidence suggests that private gun ownership and use significantly deter crime,[3] although some academics have concluded otherwise.[4][5][6][7][8][9]

Marginal deterrence[edit]

Marginal deterrence is a principle in theory of criminal justice, stating that a more severe crime should be punished more severely than a lesser crime and that a series of crimes should be punished more severely than a single crime of the same kind.[10]

Marginal deterrence is intended to deter criminals to limit their criminal acts. Without marginal deterrence, a criminal could benefit from committing additional crimes or using illegal methods to suppress law enforcement, witnesses or evidence. As an example, if robbery without force gave the same punishment as robbery by murder, a robber could make a rational choice to kill the victims to evade their testimonies.

Effectiveness[edit]

Some research has shown that increasing the severity of a punishment does not have much effect on crime, while increasing the certainty of punishment does have a deterrent effect.[11] "Clearly, enhancing the severity of punishment will have little impact on people who do not believe they will be apprehended for their actions.".

The use of 'heavy' punishment has been described as "the least effective and least fair principle of sentencing".[12] A study by a Canadian criminologist Paul Gendreau brought together the results of 50 different studies of the deterrent effect of imprisonment involving over 300,000 offenders. The report said: "None of the analyses found imprisonment reduced recidivism. The recidivism rate for offenders who were imprisoned as opposed to given a community sanction was similar. In addition, longer sentences were not associated with reduced recidivism. In fact the opposite was found. Longer sentences were associated with a 3% increase in recidivism. This finding suggests some support for the theory that prison may serve as a ‘school for crime’ for some offenders".[13]

A 2000 study by Uri Gneezy and Aldo Rustichini, A Fine Is a Price, has shown that introducing a fine for a previously unfined behavior may increase, rather than decrease, the unwanted behavior. This happens as the fine replaces a previous set of moral or ethical norms, and if it is low enough, it is going to be easier to overcome than the non-monetary criticism was. In other words, putting a price on something previously not on a market changes its perception drastically, and on occasion it can change it contradictory to what a deterrence theory would predict.[14]

The most recent studies into the matter though have found that deterrence does cause a decrease in criminal acts. A study by Prof. D.S. Abrams found that when one uses "the introduction of state add-on gun laws, which enhance sentences for defendants possessing a firearm during the commission of a felony, to isolate the deterrent effect of incarceration. Defendants subject to add-ons would be incarcerated in the absence of the law change, so any short-term impact on crime can be attributed solely to deterrence. Using cross-state variation in the timing of law passage dates, I find that the average add-on gun law results in a roughly 5 percent decline in gun robberies within the first three years. This result is robust to a number of specification tests and does not appear to be associated with large spillovers to other types of crime."[15]

Prof. Kuziemko found that sentence length has a substantial negative effect on recidivism: a three percent decline in recidivism for every extra month served.[16]

Another study using a European natural experiment uses the 1996 Bastille Day pardon in France to estimate the effect of sentence reductions on recidivism. (“[I]ndividuals who were in French prisons by Bastille Day benefited from a basic sentence reduction of one week, plus one additional week of reduction per residual month of sentence by Bastille Day, with total reduction not exceeding 4 months. By construction, this collective pardon generated a very significant discontinuity in the relationship between time served in prison and prospective date of release.”). They find that a greater sentence reduction via the pardon leads to an increase in expected future recidivism.[17]

ECON. 257, 258–60 (2009) (using a natural experiment in Italy to corroborate a general deterrence theory, finding that an extra month in expected sentence reduces the likelihood to recommit a crime by 1.3%)[18]

Eric Helland & Alexander Tabarrok found that California’s three-strikes law has a deterrent effect and reduces third-strike arrests by 17–20%); Levitt, supra note 16, at 360–70 (finding deterrence to be a more important factor than incapacitation in explaining “the negative correlation between arrest rates and crime”.[19]
