A supervisor who investigated, documented, or was directly involved in any incident shall not be assigned to conduct any subsequent inquiry/investigation (e.g., Watch Commander Service Comment Report review, civil claim review, lawsuit review, force review, administrative investigation) related to the same incident.
If no other supervisor is available to conduct a subsequent inquiry/investigation, the concerned unit commander shall notify and confer with his division chief, who shall be responsible for deciding how to accomplish the inquiry/investigation. In cases where the involved supervisor is directed to complete a subsequent inquiry/investigation, the supervisor shall document the reason(s) why he/she was directed to conduct the inquiry/investigation and the name of the manager who directed it.
