This book is an achievement on several fronts. Firstly, it represents an impressive
fusion of theoretical subtlety and sophisticated quantitative research methods. This
happens far too rarely in the policy research world that I inhabit. Secondly, the
conceptual lens through which it examines the reforms to the Chilean criminal
justice system is one that provides—to my mind—exactly the right focus that is
needed when assessing the performance of any justice system. And thirdly, it
generates some real insights into the impact of one important governmental reform
process. In this foreword, I shall discuss briefly these three themes.
