Keep an Open Mind

As an interviewer it is important to keep an open mind. Do not assume or prejudge anything. You must be prepared to believe what people might say but you must equally be on guard against deception. Whilst witnesses and victims are generally trustworthy they can invent stories to protect another party, or distract you from their own involvement. An interviewee may equally be genuinely mistaken and believe something is true when it is not.

Use your intelligence, planning and common sense. Consider what the interviewee says in the light of what you already know and against what you might be able to prove later.
