'A key take away from the book - and from each chapter within it - is the very reason such a book is necessary: there is still a long way to go. While certainly true for policing, this is even truer for security, which at the moment is quite under-researched and under-regulated. The gaps between actual practice and best practice in policing and security make it all the more important that this book is, as Prenzler says, "designed to appeal to a wide readership, including academics, students of policing and security, managers and operational officers in both fields and legislators and policy makers." Thus the value of this book lies in its power to inform a variety of professions in the same field, which is an essential step towards effecting real change within policing and security.'
