When we are engaged in an interview we are in the business of establishing the truth. (As the interviewee perceives it to be). In order to obtain accurate and reliable information it is important that we do so by not corrupting the account by introducing information or leading the interview in anyway. We do have to take our turn in the conversation but when we do so we have to minimise the risk of introducing information, or offering opinions.
The principle of effective forensic questioning follows Locards principle of exchange in forensic examination. Locard's exchange principle states that "With contact between two items, there will be an exchange. Every contact leaves a trace."
We will examine methods of questioning and conversation management which reduce the risk or trace in order to produce the finest forensic accounts for Court.
