A number of people read early drafts of the book and made extremely helpful comments, both on factual points and on larger questions of interpretation and emphasis. As always, Norman Dorsen took time away from his many responsibilities to give the manuscript a critical reading. Although I was never formally a student in one of his courses, he has been a great teacher in the broadest and best sense of the term. Gara LaMarche of Human Rights Watch, a colleague on the ACLU Board of Directors, also gave me the benefit of his considerable knowledge about this subject. Franklyn Haiman of Northwestern University and David Moshman of the University of Nebraska at Lincoln also read early drafts of many chapters and made helpful comments.
In a much wider way this book has benefited from my ten years of service on the ACLU Board of Directors. The opportunity to participate in the debates on frontier issues, where it is so often a question of responding to competing and compelling civil liberties claims, has been the best education I ever received. To my colleagues on the board and to its current president, Nadine Strossen, my thanks.
Much of the original research for this book was done for a previous work, In Defense of American Liberties. Through the process of "total incorporation"advocated by Justice Hugo Black, I should probably thank again everyone I acknowledged for that book. In particular I thank the staff of the Seeley G. Mudd Library at Princeton University, where I spent nearly six months some years ago. It was a magnificent place for research: the staff was always helpful and friendly, responding with dispatch to my constant requests for material.
