Recently, South Koreans have realized that, due to the techniques used during police investigations, suspects might often commit suicide or confess to crimes that they did not commit. Unfortunately, many studies in Korea are retrospective with regard to false confessions (i.e., case study), and no systematical research studies have been conducted on how Korean police officers interrogate suspects. To prevent events in which potentially guilty suspects are treated inhumanely and innocent suspects falsely confess, self-reported surveys were administered to 86 Korean police officers to systematically analyze how Korean police officers prepare for interrogations (e.g., interrogation training session attendance), how they initiate interrogation (e.g., obtaining Miranda waiver), how they interrogate suspects (e.g., use psychologically coercive tactics), and their opinions on videotaping interrogations. The results showed that since most Korean police officers are trained to use the Reid Technique and similar tactics—if not the same—that American police officers use, they are likely to obtain false confessions at a similar rate in comparison to American police officers.
