A ccepting evidence from many sources that policing is undergoing a historic restructuring, this report describes the forms this restructuring is taking, the reasons for it, and the issues that it raises for governance, especially with respect to the issues of justice, equality of protection, and quality of service. We believe that the current restructuring is worldwide, although information for the report is drawn more extensively from democratic countries, both developed and developing. The report does not undertake original research but, rather, explores how the topic should be studied. The report concludes with a discussion of the topics that most urgently need to be studied if contemporary developments in policing are to be understood and made responsive to public policy.
