This book, as an exploration of the European Union acquis adoption in the Turkish National Police, covers the diffusion of innovations, democratic policing, and historical background check theoretical frameworks of the TNP''s EU reforms after 2003. The research interest was about the decision mechanisms of the TNP towards reforms and the rise of democratic policing in Turkey. The study findings suggested that reforming police agencies should not be a significant problem for determined governments. Human rights violations should not be directly related with the police in any country. The data suggested that democratic policing applications find common application when the democracy gets powerful and police brutality increases when authoritarian governments stay in power. Democratic policing is an excellent tool to improve notion of democracy and to provide legitimacy to governments. However, democratic policing cannot be a tool to bring democracy, but may serve as a support mechanism for it. TNP''s EU reforms are good examples of successful organizational change. Politicians, academmicians, police managers and anyone else who has ineterst in organizational reform may read this book.
