What are the two basic requirements investigators should follow during interviews?

The two basic requirements investigators should follow during interviews are to listen and observe. Listening is crucial because it allows the investigator to understand the information being shared by the interviewee, obtaining details that may not be immediately obvious. This skill helps in gathering accurate and comprehensive data, as well as building rapport with the person being interviewed. Each nuance in their tone, hesitations, and emphases can provide valuable clues about the veracity and depth of the information.

Observing complements listening by enabling the investigator to pick up on non-verbal cues, such as body language and facial expressions, which can reveal emotions or intentions that the spoken words may not convey. These cues can indicate whether someone is nervous, confident, or potentially deceitful, all of which are important in the context of an investigation.

Together, these two skills create a robust framework for effective interviewing, allowing investigators to gather more contextual and meaningful information. The other choices involve valuable skills like asking questions or recording information, but they do not encompass the fundamental aspects of understanding an interviewee's narrative through attentive listening and observation.
