Final answer:
The police officer in Scene 11 claims they can't drink on the job due to department policy, which guides their professional conduct and aligns with their legitimate authority.
Step-by-step explanation:
According to the dialogue in Scene 11, the police officer claims they can't drink on the job due to department policy. This reflects the structured authority and rules that govern the behavior of police officers. Officers are expected to adhere to these policies to maintain professionalism and ensure the public that they are serving as legitimate sources of authority.
Police officers have defined powers and responsibilities, such as the power to issue a speeding ticket as part of their official duties. These responsibilities, however, do not extend into personal favors or actions that fall outside their job description, such as commanding a citizen to perform personal tasks like lawn mowing, which would likely draw protest from the public, illustrating that authority has its limits and is tied to official duties.
