Bunty: The primary job of police officers is keeping the peace. Since their subsidiary jobs, such as controlling traffic, hinder their performance of the primary one, people other than police officers should be hired to perform the subsidiary jobs. Naina: To perform their primary job well, police officers must have the trust of citizens. They gain that trust by performing their subsidiary jobs, which are the only functions most citizens see them fulfill. Bunty and Naina disagree with each other about ['whether the subsidiary jobs police officers perform enable them to perform their primary job effectively', 'whether the primary job of police officers is keeping the peace', 'whether police officers can effectively gain the trust of citizens', 'whether police officers need to win the trust of law-abiding citizens in order to keep the peace effectively']
