Which of the following techniques is NOT helpful in maintaining a calm environment during a crisis?

Using threatening gestures is not helpful in maintaining a calm environment during a crisis because such behaviors can escalate tension and provoke fear or aggression in individuals who may already be feeling anxious or unstable. A calm environment is essential for de-escalation, as it allows individuals to feel safe, understood, and more willing to engage in constructive communication.

In contrast, maintaining a calm demeanor, offering choices, and employing non-threatening body language are all strategies that foster a sense of safety and control for those in crisis. A calm demeanor can help to instill a sense of security, while offering choices empowers individuals, allowing them to regain a bit of control over their situation. Non-threatening body language reinforces safety, showing that the officer is not a threat, thereby minimizing the potential for conflict. Overall, promoting a peaceful atmosphere is critical in crisis management, and threats directly undermine that goal.
