The purpose of this study is to improve the problem of ‘Gapjil’ in police organizations and create a healthy organizational culture. The problem of ‘Gapjil’ undermines trust in the police organization and can have a negative impact on interactions with citizens. This study focused on deeply understanding the causes and effects of ‘Gapjil’ in police organizations and seeking improvement measures to solve these problems and form a sustainable organizational culture. To this end, we analyzed the actual situation of abuse of power occurring within the police organization to understand the causes and patterns of occurrence, clarified these problems through in-depth analysis, and prepared analysis data for improvement. Through this analysis, the following improvement measures were derived. First, providing opportunities to create a positive organizational culture, second, maintenance and inspection of existing measures, third, establishment of a damage reporting and support center and designation of dedicated staff, fourth, preparation of measures such as guaranteeing confidentiality of reporters and rules related to victim protection and support, and fifth, active participation of the head of the institution. There is a need for attention on coping and follow-up management. As a result, if the problem of ‘Gapjil’ is improved, it is expected that it will promote a healthy organizational culture in the police organization and contribute to increasing the overall efficiency of the organization and social trust.
