Conan: The One Opening the Door is the Police

I am the police. The crime scene is under our control, all non-essentials, clear out! You're a detective? Do you have a legitimate license? Are you part of the police system? Can I list you as a suspect? Great detective? Sorry, never heard of you. You want to deduce? Sorry, not interested, stand aside and watch us solve the case! Hey! Don't move anything at the crime scene, I'm talking to you, kid over there! —— Newbie's work, seeking guidance.
