ABSTRACT
This chapter reviews four main themes that are relevant to an ethical approach to criminal investigation. First, it examines the importance of ethics to investigative practice and argues that law, statements of rights and rules of procedure are not sufficient in themselves to ensure good professional conduct. Secondly, it analyses the moral dilemmas that face investigators, including those which derive from conflicting loyalties and competing value systems. Thirdly, it examines the corrosive effect of corrupt investigations on society, on the legitimacy and effectiveness of investigating organizations and on individual investigators.
