What conditions must be met to support the use of deadly force?

The correct answer emphasizes the necessity of observing the ability, intent, and action to harm a person when justifying the use of deadly force. This is grounded in self-defense and defense of others principles, where individuals must assess whether a legitimate threat exists.

Ability refers to whether the person poses a real threat of causing harm, intent reflects their intention to cause that harm, and action signifies that the individual is actively pursuing or engaged in behavior that indicates they will inflict harm. Deadly force can only be considered justifiable when all three components are observed, as this ensures that the response is proportionate to a real and immediate threat.

While other options may highlight situations where force might be applicable, they do not specifically address the criteria necessary for justifying deadly force. For instance, completing firearms training, recognizing risks to people or property, or merely witnessing a crime does not provide a clear indication of an imminent threat to life that would justify the use of deadly force. Understanding these parameters is crucial for security personnel in making ethically and legally sound decisions in critical situations.
