When can a security guard use physical force?

The correct answer emphasizes that a security guard can only use physical force when it is absolutely necessary and within the legal limits. This approach aligns with the legal framework surrounding the use of force, which dictates that any physical response must be proportional to the threat faced and should be employed only after all other options have been considered and exhausted.

Security personnel are trained to assess situations carefully and determine the appropriate level of force required to address a threat or ensure safety, which underscores the importance of legality and necessity. Using force indiscriminately or in any situation could lead to legal repercussions and professional consequences for the guard.

When examining the other options, it's clear they lack this necessary framework. Feeling threatened does not justify the use of force if it is not warranted by the situation, and apprehending suspects for minor offenses often falls outside the scope of a security guard's authority. Lastly, using force in any situation to ensure compliance disregards the critical need for appropriate, measured responses and the principles of de-escalation. This answer reinforces the balance between the need for security and the rights and safety of individuals.
