The police are a government organisation who are given responsibility for maintaining law and order.
Oh, what a great topic! We should discuss famous police departments (Scotland Yard, NYPD, LAPD, others?), the history of police, the legal distinction(s) between military and police (and lacks thereof in some societies), what training police officers are typically required to have, comparison and contrast of policing systems, and police behavior...golly, the list goes on and on.
