Why should leading questions be avoided during investigations?

Leading questions should be avoided during investigations primarily because they suggest answers to the witness. This characteristic can influence the testimony the witness provides, potentially causing them to respond based on the implied answer rather than their own recollection or understanding of the events. When a question is framed in a way that indicates a certain response, it can introduce bias into the witness's answer and distort the gathering of facts.

The goal of an investigation is to obtain accurate and unbiased information from witnesses, allowing for a clearer understanding of the events in question. Therefore, maintaining neutrality in questioning is critical. By using neutral questions, investigators can encourage witnesses to share their genuine observations and experiences without undue influence, leading to more reliable and valid evidence.
