Does a great job of explaining both the causes and the consequences of the prison-building and sentencing trends of the past couple decades, and it was eye-opening even for a californian who has followed the debate over 3 strikes fairly closely in the news. It's thorough and balanced, avoiding the simplistic victim-versus-criminal rhetoric which seems to pervade much debate on these issues. Eminently readable too, given the complicated subject. Definitely recommended...
