One of the primary responsibilities of a country is to construct safe society from the risk of recidivism as the state prevents crime and reforms criminals to reintegrate them into society. Under the current system of criminal justice procedure it is also important to punish offenders with swift measures such as arrest after the occurrence of crime. However, a serious problem of this system is to ignore the fact that a good citizen is already sacrificed with the offence. Therefore, it needs to develop preventive criminal policy which can forestall crime before a law-abiding citizen becomes victim. It is particularly significant to create preventive criminal policy as it can contribute to realization of constitutional value based on respect for people as well as establishment of practical utopia to seek happy life of all citizens.
