Rapport‐Building During Witness and Suspect Interviews: A Survey of Law Enforcement

Building rapport with adult witnesses and suspects is recommended by major investigative interviewing protocols (e.g., Cognitive Interview and the Army Field Manual in the USA and PEACE in the UK). Although recent research suggests that building rapport can sometimes benefit police investigations by increasing the accuracy of adult eyewitness reports and potentially enhance the diagnosticity of evidence obtained from suspects, little data exist regarding how law enforcement interviewers actually define and build rapport in real‐world investigations. To fill this void, the present study distributed a questionnaire containing open and closed‐ended questions to 123 law enforcement interviewers in police training courses to determine how they conceptualize and build rapport with adult interviewees. Results indicate that a majority of law enforcement interviewers define rapport as a positive relationship involving trust and communication, with a strong minority defining rapport as a ‘positive or negative’ relationship. Further, law enforcement interviewers reported building rapport with adult witnesses and suspects in a similar manner, often by using verbal techniques (e.g., discussing common interests via small talk) and non‐verbal techniques (e.g., displaying understanding via empathy and sympathy). Theoretical and applied implications of these results are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
