When is an officer justified in using force against a person in custody?

The correct answer about when an officer is justified in using force against a person in custody is maintaining security in a penal institution. This justification encompasses a broader need to ensure the safety and security of both inmates and staff within the facility. The use of force can be essential in managing unruly behavior, riots, or other circumstances that may threaten the order of the institution.

Maintaining security is crucial because it helps prevent incidents that could lead to harm or disruption. Correctional officers often face situations where immediate action is required to secure an environment that protects the rights and safety of all individuals within the facility.

While preventing escape, protecting personal safety, and enforcing discipline are also valid considerations for using force, they typically fall under the broader umbrella of maintaining security. Each of these situations can indeed warrant a response, but the overall objective revolves around keeping the prison or jail secure and ensuring that order is upheld, which takes precedence in the context of force application in custody situations.
