Arranging the seating to minimize interference is a key strategy for facilitating better observation of a suspect’s behavior during an interview. This approach creates an environment that allows the interviewer to maintain focus on the suspect's non-verbal cues, facial expressions, and overall demeanor without unnecessary distractions. By positioning the seating to foster clear lines of sight and promote an interactive dialogue, the interviewer can better assess the suspect's reactions and responses, which are critical for gathering information and detecting deception.
In contrast, allowing distractions in the environment, positioning all parties directly opposite one another, or conducting the interview in a large crowd would likely create barriers to effective observation. Distractions can divert attention away from the suspect’s behavior and impact the quality of the interview. Similarly, directly opposing seating can lead to a confrontational atmosphere, hindering open communication. Conducting the interview in a crowded space can introduce multiple distractions and complicate the ability to read the suspect's behavior effectively. Hence, arranging the seating to minimize interference is the most conducive approach for careful observation during the interview process.
