When handling multiple witnesses to an incident, it is crucial to separate them to avoid influence from one another. This approach helps ensure that each witness provides an independent account of what they observed, which can lead to more reliable and accurate information. If witnesses are allowed to interact or discuss their observations, it can result in altered memories or shared narratives that may not reflect what each individual truly experienced.

By separating witnesses, law enforcement can gather diverse perspectives and details about the incident that could be critical for the investigation. This method supports the integrity of the witness statements and enhances the overall quality of the evidence collected. In contrast, the other options may compromise the reliability of the information gathered, as they either encourage group dynamics that can distort individual memories or do not prioritize the independent assessment of each witness's account.
