Would a possible offender lie during an interview - If so, how can we detect deception scientifically

This essay explores how physical expressions of deception, in the context of communication, affects interviewing within the criminal justice system. Body language as cues to deception are explored in the study by Wright & Wheatcroft (2017) “Police officers' beliefs about, and use of, cues to deception” and the influence of eye contact with the study by The Global Deception Research Team (2006) “A World of Lies.” This essay uses as a case study The Confession (2010a), the police interview of Colonel Russell Williams in connection with the murder of two women in his locale. Commentary is informed by the studies of Wright and Wheatcroft (2017) and The Global Deception Research Team (2006).
