Honestly, there's a part of me that feels like the detective was a part of the rape and murder of Wataru's sister, like maybe he was paid off to get the criminals a lighter sentence or something. I could be wrong, but it just feels like the detective does a lot to protect the criminals in the name of upholding the law, but he uses methods that seem pretty illegal, especially considering he has no physical evidence connecting Wataru to the murders and therefore no probable cause to be doing any of this nonsense.
