John Paul Stevens in the New York Review of Books:
William Stuntz was the popular and well-respected Henry J. Friendly Professor of Law at Harvard University. He finished his manuscript of The Collapse of American Criminal Justice shortly before his untimely death earlier this year. The book is eminently readable and merits careful attention because it accurately describes the twin problems that pervade American criminal justice today—its overall severity and its disparate treatment of African-Americans.
The book contains a wealth of overlooked or forgotten historical data, perceptive commentary on the changes in our administration of criminal justice over the years, and suggestions for improvement. While virtually everything that Professor Stuntz has written is thought-provoking and constructive, I would not characterize the defects in American criminal justice that he describes as a “collapse,” and I found his chapter about “Earl Warren’s Errors” surprisingly unpersuasive.
Rather than focus on particular criminal laws, the book emphasizes the importance of the parts that different decision-makers play in the administration of criminal justice. Stuntz laments the fact that criminal statutes have limited the discretionary power of judges and juries to reach just decisions in individual cases, while the proliferation and breadth of criminal statutes have given prosecutors and the police so much enforcement discretion that they effectively define the law on the street.
