This study examines the effects of sex crime on social life. It is based on the theory that prevention of motives for sex crimes is a major deterrent to sex crimes in order to control security policies and sex crimes. Human beings are born with good hearts regardless of gender. Also, they are determined to pursue their dreams and future-oriented life, work life in a good environment, economic stability and success in the future (Kim Deuk-Joong, 2006: 46). However, those who are not prepared to pursue such a happy life will neglect their efforts and lose the heart of Vaughn, whose purity is almighty and egoistic. Eventually, they cannot adapt to society and fall into temptation of crime to solve their shortages. In addition, the development of capitalism following the industrial revolution in the late 19th century, the increase of crime, the accusation and juvenile crime are increasing. The cause of this phenomenon, the first line of police organizations that are in charge of the investigation to prevent the early detection and recurrence of sex crimes, as well as the administrative and administrative level of the government has been taken seriously. An important part of the police investigation, which is the core of civil security, plays a pivotal role in criminal activity, and the expectations and interests of the citizens are symbolic of the interests of a large fulfillment condition in a symbolic sense. Compensation issues should also be actively protected. Therefore, the punishment and promptness should be preceded by grasping the causes, proactive prevention, and psychological analysis of sex crimes, and the cost of investigation should be set smoothly by increasing the number and special recruitment of the investigation police.
