Final answer:
Non-disposition is the term used when an officer did not do what the citizens claimed, indicating that there's insufficient evidence or the claim is false.
Step-by-step explanation:
The type of disposition when the officer didn't do what the citizens said they did is Non-disposition. A non-disposition occurs when an accusation or complaint is not substantiated, meaning there's insufficient evidence or the allegation is proven to be false. This term is often used in the context of police or law enforcement when reviewing the outcomes of investigations into officers' conduct. In contrast, mis-disposition, over-disposition, and under-disposition do not accurately describe this scenario and are not commonly used terms in this context.
In this scenario, the officer failed to accurately record and document the information provided by the citizens. This can happen due to negligence, bias, or other factors that may affect an officer's judgment and actions.
