In Saga Prefecture, a scandal has emerged involving a forensic technician at the local police department who was dismissed for tampering with DNA test results. This situation has led to calls for an independent third-party investigation into the matter. However, the police department has responded by stating that the Public Safety Commission, which possesses third-party neutrality, is overseeing the investigation without needing external verification. This response raises questions about the effectiveness of the commission and its oversight capabilities in this serious incident.

The Asahi Shimbun, while investigating the situation, submitted a request for the disclosure of materials related to discussions within the Public Safety Commission. In response, the police provided documents that revealed the commission's involvement in the cases of improper DNA assessments. The disclosures included reports from meetings held from January to August of the previous year, during which the DNA testing fraud issue was discussed on six occasions. However, many details, including the names of some commission members, have been redacted, which diminishes the transparency of the findings.

One highlighted detail was a report from a January meeting showing that a technician had been falsifying DNA testing documentation, creating false periods of performance for tests between 2017 and 2024, and neglected to submit conclusions for an extended duration afterward. This series of events raises serious concerns about the integrity of DNA testing processes in criminal investigations and highlights the need for accountability within the police structure, as well as the importance of scrutiny from independent oversight bodies to maintain public trust.
