Having background information on the person or situation before interviewing is a good idea.

• A. Not necessary
• B. True
• C. Only for suspects
• D. False

Answer: (B)

Preparation before interviewing is essential. Having background information on the person or situation before you begin helps you understand the context, tailor your questions to be relevant, and guide the conversation so you don’t miss important leads. It also supports safety, helps build appropriate rapport, and aids in spotting inconsistencies later by knowing what would be typical given the background. This approach applies to suspects, witnesses, victims, or subject-matter experts alike, so it isn’t limited to any one group. For these reasons, having background information beforehand is a good idea.
