Which of the following is an example of a security breach in a court building?

An example of a security breach in a court building is when an individual enters with a prohibited item. This situation directly undermines the safety protocols established to maintain a secure environment within the courtroom and court facilities. Prohibited items typically include weapons, explosives, or any objects that could potentially harm individuals or disrupt court proceedings. When such an item is brought into the court premises, it poses a significant risk not only to the personnel and visitors within the court but also affects the integrity of the judicial process itself.

In contrast, events such as a fire alarm going off, a power outage, or a long line at the security checkpoint, while they may involve disruptions or concerns, do not represent intentional breaches of security protocol. A fire alarm may indicate an emergency situation that requires evacuation but is a safety measure rather than a security violation. A power outage impacts functionality and operations but does not directly relate to unauthorized access or safety risk posed by individuals. Similarly, a long line at the security checkpoint is a logistical issue rather than a breach of the established security measures. Thus, bringing in a prohibited item stands out as a clear violation of security norms within a court setting.
