You Were Asked to Catch the Murderer, but You Arrested Everyone Who Was Handling the Case?

In my thirty years as a police officer, I have seen the most cunning murderers and heard many tearful stories. I once saw an eighteen-year-old boy who, just to compete with his younger brother for favor, made his younger brother into a living human skin lantern. I once heard of a mother who, in order to prevent her second-married husband from violating her daughter, smashed her husband's skull into pieces while he was still alive. In real life, someone is committing a crime every minute. Who knows whether his next target will be you?
