This conclusion presents some closing thoughts on the concepts discussed in the preceding chapters of this book. The book explores the role of the prosecutor across different jurisdictions. It explores the main conclusions drawn from individual chapters and from across the collection as a whole. The book identifies the areas of omission and to propose a future research agenda for ongoing study of the roles of the prosecutor. The most notable of these is the growing power of prosecutors in both common law and civil law jurisdictions. Prosecution systems are evolving to meet challenges that are either new or newly recognized. These include better meeting the needs of victims, protecting suspects from wrongful convictions, addressing the challenges of particular kinds of offending and involving "the community" more directly and actively in the processes for responding to offending.
