This Article discusses the deterrence of crime through sanctions. It begins with a brief intellectual history of deterrence theory in the work of Cesare Beccaria and Jeremy Bentham, two Enlightenment philosophers who created the conceptual foundation for later deterrence and rational choice theory. Although a prominent intellectual current by the end of the 1700s, interest in deterrence and rational choice based theories of criminal offending was later eclipsed by more biologically and psychologically based explanations. Interest in deterrence theory and the deterrent effect of legal sanctions was not rekindled until the mid-1960s. This Article discusses the particular and important role of the Journal of Criminal Law and Criminology in publishing the works of both those who were highly critical of deterrence theory and those who wished to keep it alive, though vividly aware of the lack of any empirical support for it. This Article discusses the theoretical connections that are presumed by the deterrence process and briefly reviews some important empirical studies pertaining to each of those presumed causal connections. The empirical evidence leads to the conclusion that there is a marginal deterrent effect for legal sanctions, but this conclusion must be swallowed with a hefty dose of caution and skepticism; it is very difficult to state with any precision how strong a deterrent effect the criminal justice system provides. At the very least, there is a great asymmetry between what is expected of the legal system through deterrence and what the system delivers. There is greater confidence that non-legal factors are more effective in securing compliance than legal threats. It is argued that the empirical evidence does support the belief that criminal offenders are rational actors, in that they are responsive to the incentives and disincentives associated with their actions, but that the criminal justice system, because of its delayed imposition of punishment, is not well constructed to exploit this rationality.

The concept of deterrence is quite simple - it is the omission of a criminal act because of the fear of sanctions or punishment. While not the entire premise, deterrence is certainly an important foundation of the criminal justice system. Law enforcement exists both to apprehend wrongdoers and to convince would-be wrongdoers that there is a risk of apprehension and...
