Rendition is the practice of detaining a terrorist operative in a foreign country and transferring him or her to the U.S. or to another foreign country. It has proved to be an effective way to take terrorists off the street and collect, on occasion, some valuable information. However, the U.S. Government's use of rendition has been extremely controversial. This book explores the use of extraordinary rendition and its impact on transatlantic relations, the constraints imposed by laws on torture, and looks at the background and legal issues of undisclosed U.S. detention sites overseas.
