What is the term for using reasonable force to protect oneself or others as a security guard?

The term that refers to the use of reasonable force to protect oneself or others as a security guard is self-defense. Self-defense is a legal concept that allows a person to use reasonable amount of force to prevent harm to themselves or others. It is generally recognized that individuals have the right to defend themselves from imminent threats or harm, provided that the force used is proportional and necessary in the situation at hand.

This principle ensures that security guards can act effectively in potentially dangerous situations without facing legal repercussions, as long as their response is appropriate to the threat they are encountering. Understanding self-defense is crucial for security professionals, as they often find themselves in situations where quick decisions about the use of force are required to ensure safety.

The other options represent different concepts or situations. Excessive force refers to the application of more force than is necessary in a situation, which can lead to legal issues and is not considered acceptable. Restraint typically pertains to holding someone to prevent them from acting, but does not address the use of force in a self-protection context. Detainment relates to the act of holding someone against their will for questioning or investigation, which is also distinct from the concept of using force for protection.
