Which of the following is not an acceptable use of force?

The use of force within any security framework is governed by strict guidelines that emphasize the necessity of appropriateness and proportionality. In this context, striking back or employing unlawful force is not an acceptable use of force because it violates these principles. This approach undermines the legality and integrity of security practices, as it can escalate situations unnecessarily and may also lead to legal repercussions for the individuals involved.

In contrast, verbal confrontation is often a de-escalation tactic, where individuals are trained to communicate effectively to resolve conflicts without physical intervention. Preventive measures are proactive actions taken to avert potential incidents before they escalate. Additionally, physical restraint may be deemed appropriate in scenarios where there is an imminent threat to the safety of individuals, and it is executed in a way that complies with policy and training guidelines. Thus, the emphasis is always on using the minimum necessary force in response to a given situation, with the goal being to protect and ensure the safety of all parties involved.
