What should a PSO use to gather information when receiving a bomb threat via telephone?

Using the DHS bomb threat information note card is essential when receiving a bomb threat via telephone because it is specifically designed to help the PSO document vital information during the call. This note card prompts the officer to ask critical questions to the caller, such as the location of the bomb, the time it is set to detonate, and any additional details about the threat. Collecting accurate and thorough information is crucial for responders to assess the situation and implement appropriate actions.

The other options do not serve the intended purpose as effectively. The DHS activity log form is more suited for tracking general activities and does not focus specifically on bomb threat details. The DHS bomb threat stand-off chart may assist in determining safe distances during a response but does not aid in gathering information during the initial threat call. The DHS offense/incident report form is generally used for documenting completed incidents rather than collecting real-time information from a threatening situation. Therefore, the bomb threat information note card is the best tool for this specific context.
