What is crucial to do before conducting an interview?

Preparing for the interview is essential because it sets the foundation for a successful information-gathering session. Preparation involves understanding the case background, formulating specific questions, and being aware of the legal considerations surrounding the interview process. This preparation allows the interviewer to engage more effectively with the interviewee, ensuring that pertinent details related to the fire or explosion are not overlooked.

Additionally, preparation helps to create a comfortable environment for the interviewee, making them more likely to provide accurate and useful information. Without adequate preparation, the interviewer risks missing crucial information or failing to ask relevant questions that could impact the investigation's outcome.
