A theory that criminal laws are passed with well-defined punishments to discourage individual criminal defendants from becoming repeat offenders and to discourage others in society from engaging in similar criminal activity
Deterrence is one of the primary objects of the CRIMINAL LAW. Its primary goal is to discourage members of society from committing criminal acts out of fear of punishment. The most powerful deterrent would be a criminal justice system that guaranteed with certainty that all persons who broke the law would be apprehended, convicted, and punished, and would receive no personal benefit from their wrongdoing. However, it is unrealistic to believe that any criminal justice system could ever accomplish this goal, no matter how many law enforcement resources were dedicated to achieving it.
As a result, philosophers, criminologists, judges, lawyers, and others have debated whether and to what extent any criminal justice system actually serves as a deterrent. Deterrence requires the would-be criminal to possess some degree of reflective capacity before the crime is committed, at least enough reflection to consider the possible consequences of violating the law if caught.
Since many crimes are committed during "the heat of the moment" when an individual's reflective capacities are severely compromised, most observers agree that some crimes simply cannot be deterred. Individuals who commit crimes for the thrill of "getting away with it" and outwitting law enforcement officials probably cannot be deterred either. In fact, such individuals may only be tempted and encouraged by law enforcement claims of superior crime-prevention and crime-solving skills.
