Which of the following questions is probably NOT acceptable when interviewing a witness?

The question regarding whether the witness saw a girl with blue hair steal the purse is likely not acceptable because it assumes a specific detail about the suspect that has not been established by the witness. This type of question can lead to suggestive or leading responses, which can influence the accuracy and reliability of the witness's account. In contrast, the other questions are open-ended or straightforward inquiries that allow the witness to provide information based on their own observations without implying any specific narrative. Asking witnesses to describe what they saw without leading them helps to ensure that the information collected is more accurate and unbiased, which is crucial for effective police reporting and investigation.
