"This impressively researched book makes an important contribution to a wide range of central themes in modern American history, including the growth of state power and the policing of class, race, and gender relations. In this age of terrorism, 'homeland security' initiatives, the expanded use of wiretapping and other forms of surveillance, and a new debate about the relationship between civil liberties and governmental authority, New York Undercover is also timely." - Jeffrey Adler, University of Florida"
