Book excerpt: In this book, Erik Luna and Marianne Wade examine the considerable powers of the American prosecutor and look abroad in order to learn valuable lessons from a transnational examination of prosecutorial authority. They explore parallels and distinctions in the processes available to and decisions made by prosecutors in the United States and Europe. Through the varied topics covered by the contributors on both sides of the Atlantic, they demonstrate how the enhanced role of the prosecutor represents a crossroads for criminal justice with weighty legal and socio-economic consequences.
