After 9/11, serious questions were raised as to the methods that might be used to extract information from terrorists who might threaten U.S. national interests. What constitutes torture? Is it ever justified? What are the legal procedures that the U.S. government can put in place regarding this issue? Jean Bethke Elshtain of the University of Chicago; Sanford Levinson of the University of Texas Law School, who edited a new book of essays titled Torture: A Collection; Kim Scheppele of the University of Pennsylvania Law School; and former Justice Department official John Yoo of AEI and the University of California–Berkeley—will discuss the philosophical, moral, and practical implications of the use of torture for gathering intelligence.
