Dress code. Maybe someone can explain this to me. Riggs and Murtaugh are cops, right? Then why do they dress like that, and not like this? The same goes for John McClane.. Once again... why? Now, in real life, do cops actually get away with this dress code? Here are some key questions: - What is the difference between an officer, a lieutenant, a sargeant, a detective, a captain, a chief of police, a commissioner.... etc? - officer - lieutenant - sargeant - detective - captain - chief of police - commissioner ^^ And what is the dress code for each? Another example: James Gordon... Or Mills and Somerset... Can anyone please explain????
