Conan: Open the Door, I’m a Policeman

Novel Summary
I’m a policeman, we took over the crime scene, and all the idlers and other people flashed!
Are you a detective? Do you have a formal license? Is it part of the police system? May I list you as a suspect?
Detective? Sorry didn’t hear it.
You want to reason? I’m sorry I’m not interested, but I’m standing there watching us handle the case!
Hey! Don’t move around at the crime scene, it’s you, that kid over there!
