Final answer:
The question seems incomplete as it lacks specific details on officer requirements for each shift. To determine officer requirements for scheduling, one would need the number of officers needed per shift and the total number of officers available, which is not provided here.
Step-by-step explanation:
The question provided requires an analysis of shift schedules and staffing requirements at a police department, which is a mathematical problem of optimization and resource allocation. However, the question seems to be incomplete, as it does not specify the exact officer requirements for each of the two 6-hour shifts at the Gotham City Police Department (GCPD).
Without this information, it's not possible to determine the exact number of officers required for each shift. To solve a problem like this, one would typically need to know how many officers are necessary for each shift as well as any special requirements such as certain skills or ranks. Knowing the total number of officers available for duty would also be necessary.
This type of problem could involve linear programming, scheduling algorithms, or other operation research techniques to optimize staffing.
Details provided in the question text related to police force size and the nature of police work, such as the number of sworn personnel and distinctions between local and federal law enforcement, do not directly answer the student's question about shift requirements.
These details, while informative about the broader context of law enforcement employment, do not provide the necessary data to calculate shift scheduling.
