A formal bomb search initiated by the local authorities is called

• A. Security sweep
• B. Police search
• C. Threat assessment
• D. Bomb drill

Answer: (B)

Understanding the type of response to an explosive threat hinges on recognizing who initiates and conducts the operation. When local authorities initiate a formal search for bombs, it signifies an official law enforcement response carried out by the police. This label conveys that the action is commanded, regulated, and carried out under government authority, often with coordinated procedures, cordons, evacuations, and specialized units like a bomb squad if needed.

A security sweep, while similar in purpose, is usually conducted by security personnel and may occur in venues or facilities as a preventive measure or part of ongoing security operations, not necessarily as an official police action. A threat assessment focuses on evaluating risks and likelihoods rather than performing a physical search for devices. A bomb drill is a training exercise to practice responses, not an actual search or investigation.
