In what situation can a security officer use deadly force?

The correct choice specifies that a security officer is permitted to use deadly force only in circumstances of self-defense or defense of another person from imminent harm. This aligns with the principles of both self-defense laws and the rules governing the use of force in security contexts. It is crucial to understand that deadly force is a last resort action and is only justified when there is an immediate threat to life. The law requires that such force be proportionate and necessary to prevent serious bodily injury or death, reinforcing the idea that the officer must be in genuine fear for their safety or the safety of others.

The situation does not allow the use of deadly force for less urgent scenarios, such as simply detaining a suspect for theft, as theft does not typically pose an imminent threat of serious bodily harm. In the case of a robbery in progress, while the circumstances may be dangerous, the law generally still emphasizes the necessity of a clear and immediate threat to justify the use of deadly force. Additionally, feeling threatened verbally does not legally justify the use of lethal measures, as threats must be tangible and immediate to warrant such extreme action. This distinction is fundamental within security practices and legal frameworks surrounding the use of force.
