Even as the author proposes the promotion of deterrence as a goal of the criminal justice system, they are fully aware that the goals of correction are closely related(Aberson and Jenion 170). As a consequence, one goal cannot be pursued in isolation from the others. Rather, the goals need to be pursued concurrently. For instance, punishment may be expected to lead to deterrence in at least two ways. First, when the authorities increase the certainty of punishment, potential offenders may be deterred from the fear of being apprehended. Secondly, if the punishment is severe enough, potential offenders may decide to avoid crime. Deterrence theory assumes that human beings, including potential offenders, are rational and that they carefully consider the repercussions of their actions prior to committing them. However, this is not always the case. For instance, a person who commits a crime under the influence of drugs cannot be said to have been rational at the time of committing the crime.Over the years, criminological research has shown that, overall, increasing the certainty of punishment generates more deterrence than making the punishment more severe (McAlinden 389). If people are known for certain that when they commit a crime or offense they will be arrested, they will refrain from committing the crime or the offense. In reality, however, many offenses and crimes go unapprehended. Thus, a potential offender will go ahead and commit an offense even if the consequences are dire, provided that they know that the chances of them being arrested are slim. The implication for policy-makers and law-enforcement agencies to enhance their capacity to apprehend offenders. Unfortunately, law-enforcement agencies are cumbered with limitations of personnel and equipment. As a work-around to this challenge, the idea of community policing has been floated and attempted in many jurisdictions.The rationale behind the idea of community policing is that by virtue of their interactions, the members of a community know one another better than the police do (Hugh and Taylor 10). Consequently, it is easier for the members of the community to apprehend criminal behavior among them and report the same to the police. Community policing calls for a great sense of community participation.
