ABSTRACT
This chapter assesses the varying and at times overlapping roles of investigators and lawyers, considering their relationship to one another and their roles in investigations, including interviewing suspects as a case study activity that effectively demonstrates how the role of the prosecutor varies from domestic to international systems. A comparison of the backgrounds of the investigators and the lawyers is provided, and then assessment of how these differences matter with regards to interviewing suspects. The analysis demonstrates how the role of lawyers as prosecutors in an international context evolves from the experience at domestic level. The chapter provides an overview of the role of the police and the prosecutor in national jurisdictions. It focuses on the two Western legal traditions law systems: the adversarial or common and the inquisitorial or civil. In the criminal justice system, the people are represented by two separate yet equally important groups: the police, who investigate crime and the district attorneys, who prosecute the offenders.
