What is required for a person to use force to protect a third person?

To use force in defense of a third person, it is essential to demonstrate a belief that there is an imminent threat against that individual. This requirement stems from the principle of necessity in self-defense laws. The person intervening must genuinely perceive that the third party is in immediate danger, justifying their decision to step in and potentially use force to prevent harm.

This belief must be based on a reasonable understanding of the situation at hand. If a person acts without a belief in imminent danger, the use of force could be deemed unwarranted or excessive, which could lead to legal consequences. Therefore, having a belief in the existence of a clear and urgent threat is crucial for legally and ethically justifying the use of force in these scenarios. This standard aims to ensure that actions taken to protect someone else are both necessary and appropriate for preventing harm.
