What is the first step officers should take during an interview with a witness?

The initial step officers should take during an interview with a witness is to identify and isolate the witness. This process is crucial as it ensures that the witness can provide their account of the events without outside influence or contamination from other individuals who may have different perceptions of the incident. By isolating the witness, officers can create a controlled environment that allows for a more reliable and candid testimony.

This step helps in preserving the integrity of the information provided, as the witness can express their thoughts and memories without being swayed by others' opinions or statements. It also allows officers to build rapport with the witness, making them feel comfortable and valued during the interview process. Through this careful approach, officers can obtain a clearer and more accurate version of events, which is essential for any subsequent investigation or legal proceedings.
