What concept underlies the justification of certain uses of physical force?

The concept of necessity underlies the justification of certain uses of physical force, particularly in the context of law enforcement and corrections. It refers to the idea that the use of force may be warranted when it is required to prevent harm, protect individuals, or manage a situation when there are no viable alternatives. In other words, the use of physical force is considered necessary when it is used to address an immediate threat or protect the safety of individuals involved.

For instance, if a corrections officer encounters a situation where an inmate poses an imminent danger to themselves or others, the officer may have to use physical force to neutralize that threat, thereby justifying their actions under the principle of necessity. This principle emphasizes a measured and reasoned approach, ensuring that any physical force applied is proportionate to the situation at hand.

While retaliation, deterrence, and rehabilitation play roles in the broader scope of criminal justice and corrections, they do not specifically justify the immediate use of physical force in a situation where the safety of individuals is at risk. Thus, necessity is the correct and most relevant principle in this context.
