Who investigates any discharges of firearms by retired members?

The Criminal Investigation Division (CID) is the appropriate authority responsible for investigating discharges of firearms by retired members. This division is specialized in handling serious incidents involving allegations or potential misconduct, ensuring thorough and objective investigations. Their expertise is crucial in maintaining accountability for actions taken by individuals with a law enforcement background, even after retirement.

While other agencies, such as the Federal Bureau of Investigation or local police departments, may have overlapping responsibilities in certain contexts, CID specifically focuses on internal investigations relating to department members and their conduct. The Internal Affairs Division, while also tasked with investigating member conduct, primarily focuses on active officers and official complaints against them rather than incidents involving retired members. Therefore, CID is the correct choice for addressing firearm discharges by those no longer active in the force.
