"In Deceptive Ambiguity, Dr. Roger Shuy, founder and doyen of Forensic Linguistics in the US, once more reveals his genius for explaining the linguistics of real-world situations. Deception is a much-discussed area of the field, and one he has written on repeatedly throughout the years. But here Shuy's focus is specifically on how those who have control of the communicative situation can and do use ambiguity to deceive. He demonstrates-through detailedanalyses of case after case that he himself consulted on-how manipulation can be effected beneath the surface of conversational participants' conscious awareness. In this highly accessible text, Dr. Shuydemonstrates that in the legal arena, such use of deceptive ambiguity can be the equal province of lawyers, prosecutors, and police, and not just the far more studied deceptive suspects."-Robert A. Leonard, Director, Graduate Program in Forensic Linguistics, Hofstra University"Roger Shuy never seems to run out of original ideas. In this latest book, he brings his learning, experience, and insight to bear to illuminate a subtle but significant new topic in language and law: the calculated use of ambiguity in law enforcement's exercise of power. As always, Shuy's blend of sophisticated linguistic analysis and clarity of expression will appeal to both professional and lay audiences."-John Conley, William Rand Kenan Jr. Professor ofLaw, University of North Carolina School of Law"In this book, Roger Shuy, the dean of American forensic linguistics, advances our understanding of ambiguity in legal arenas beyond written texts to speech, and our understanding of deception beyond defensive talk to its institutional exploitation through ambiguity. His case studies demonstrate how commonplace 'deceptive ambiguity' is in pursuit of a desired goal in police interrogation, courtroom examination, and undercover sting operations. His analysis ofinstitutionalized ambiguity should awaken legal scholars and policy makers to the contradictions inherent in the interactional patterns ordinary citizens bring to the genres of civicinstitutions."-Edward Finegan, Professor Emeritus of Linguistics and Law, USC Gould School of Law
