Body language alone (e.g., avoiding eye contact) cannot be taken as proof of deception. The Manual warns against drawing conclusions from a single behavioral cue:

“Avoiding eye contact is not directly linked to deception. Such behavior could stem from cultural norms, nervousness, or personality traits. Examiners should consider clusters of behavior, context, and corroborating evidence before concluding deception”.

Therefore, C is correct.

The best practices for signed statements include:

Adding omitted facts as an addendum.

Preparing separate statements for unrelated offenses.

Having witnesses to the signing.

But:

“The signed statement should be reduced to a short and concise written statement. The interviewer should prepare the statement and present it to the confessor for his signature” .

Thus, requiring the suspect to handwrite the entire statement is not a best practice.

The manual explains:

“Link analysis is very effective for identifying indirect relationships… and is particularly useful when conducting a money laundering investigation because it can track the placement, layering, and integration of money” .

Therefore, statement A is false, making it the correct choice.

Best practice is to conduct interviews individually. The Manual states:

“When conducting interviews, witnesses should be interviewed separately. Interviewing multiple witnesses together risks contamination of testimony and reduced reliability of responses”.
