As the person on duty, what action should you take concerning the witnesses of the robbery?

The correct action in this scenario involves recording the names and addresses of the witnesses. This step is essential as it establishes a clear record of who witnessed the incident, which is crucial for any subsequent investigation. The names and addresses will allow law enforcement to follow up with these individuals for further questioning if necessary. Having accurate contact information helps ensure that no potential leads or pertinent information are overlooked.

Taking written statements, while important, typically comes after gathering basic information such as names and addresses. Engaging in discussions about the details of the robbery without proper protocol could lead to contamination of the witnesses' accounts or misinformation. Also, asking witnesses to gather evidence is not advisable, as it can compromise the integrity of the evidence collected and the scene itself; as trained professionals, the authorities are responsible for that aspect of the investigation.
