Engaging in physical restraint is justified primarily in situations that require immediate action to ensure the safety and well-being of oneself or others. This principle is grounded in the understanding that physical restraint should never be used lightly or on a whim; it must be a method of last resort when all other de-escalation strategies have been exhausted or are deemed insufficient.

In circumstances where there is an imminent threat of harm—such as an individual exhibiting violent behavior posing a danger to themselves or others—physical restraint can be crucial for preventing injury or even saving lives. The key focus here is on necessity and appropriateness, reinforcing that such actions should be proportionate to the threat and taken with careful consideration.

Other options fail to capture the critical standard of necessity that governs the use of physical restraint. Disagreeing with a decision, attempting to prevent someone from leaving a conversation, or reacting to any tense situation without a clear basis for concern does not meet the threshold for physical restraint. Each of these scenarios lacks the immediate necessity for protecting safety, which is the core principle guiding the use of force or restraint in security contexts.
