Writing a Medical Notes: Research on Light

You can call me Dr. Jiang, and what you will see is the investigation experience of me and Officer Yu. It mainly records the serial murderers we have encountered who claim to be "light" such as "theatre", "beheading", "skinning", etc. Due to "fighting". In fact, I don't know whether what they did was right or wrong, but from a legal perspective they did violate our country's criminal law. Officer Yu and I need to arrest them and hand them over to the law. (By the way, Officer Yu and I have normal sexual orientations.)
