[email protected] Customs officers are an understudied population in psycho-legal research. The present study is an attempt to fill this gap by examining customs officers’ interview strategies. Specifically, in an experimental setup, we examined how customs officers (N = 80) planned to use evidence in an investigative interview. Half the customs officers were members of a crime-fighting unit (less experienced interviewers) and half were members of an investigative unit (more experienced interviewers). Participants were randomly assigned to two evidence conditions: weak or strong. Participants extracted evidence from a mock crime brief and described how they would use this evidence in a suspect interview. Of the extracted pieces of evidence only 15% were planned to be used in a strategic manner. Evidence strength did not influence whether participants planned to use evidence strategically. The results showed that members of the crime-fighting unit were less likely to use evidence strategically than members of the investigative unit. Completed training courses were associated with an improvement in the planned use of evidence.
