Though the characters in “Officer Black Belt” aren’t directly modeled on real people, their concept draws from a grain of reality. In South Korea, a law enforcement measure was put into practice where high-risk criminals were monitored closely by attaching GPS tracking devices to their ankles. The intention behind this was to enhance the safety of cities like Seoul by identifying and locating violent individuals and chronic offenders with criminal records more easily. However, privacy concerns arose among the public, leading to discussions about the effectiveness of such a policy.

Since 2008, the Korean tracking policy has stayed in effect. Not only is the policy significant, but the authenticity of “Officer Black Belt” also extends to its core concept. In this policy, actual martial artists from Korea were enlisted to aid probation officers when routine arrests became heated verbal or physical disputes. These martial artists would intervene physically if required and assist during interviews as well. This fundamental law forms the basis for the narrative of “Officer Black Belt”, with writer/director Joo-Hwan Kim using firsthand accounts to enrich the storyline.
