Experts, thank you for waiting. It's the self-explanatory Policemate. The following is a side note. The main differences between the National Research Institute of Police Science (NRP) and the Forensic Science Laboratory (FSL) are the affiliated organizations and research content. The National Research Institute of Police Science (NRP) is a national institution belonging to the National Police Agency, and its staff are national civil servants who conduct basic technology research and development. On the other hand, the Forensic Science Laboratory (FSL) is an institution belonging to each prefectural police department, and its staff are local civil servants who conduct research closer to the scene, such as examining (analyzing) materials from crime scenes.
