QUE According to the ACAMS Study Guide, one of the skills of an effective AML investigator is to conduct investigative interviews using appropriate techniques and methods1. One of the techniques is to use open-ended questions that elicit detailed responses from the interviewee, and to avoid leading or suggestive questions that may reveal the investigator's assumptions or suspicions1. Therefore, the best option is to ask question of a material nature about the suspected false statements without revealing the suspected deception, as this would allow the investigator to gather more information and evidence, and to test the consistency and credibility of the interviewee's answers.
The other options are not advisable or effective, because:
A . Informing the suspect that deception is obvious and continuing the interview is not a good strategy, because it may antagonize the suspect and make them less cooperative or more defensive. It may also alert the suspect to the investigator's knowledge and sources, and give them an opportunity to change or modify their story2.
B . Advising the suspect that the interview will be terminated if there is suspicion of deception is not a good strategy, because it may create a negative impression of the investigator and the investigation, and it may discourage the suspect from providing any useful information. It may also imply that the investigator has insufficient evidence or authority to pursue the case2.
C . Directing the interview in another direction until there is better rapport before returning back to the troubling question is not a good strategy, because it may waste time and resources, and it may lose the focus and momentum of the investigation. It may also signal to the suspect that the investigator is not confident or competent, and it may give the suspect a chance to prepare or rehearse their answers2.
