Jack L. Goldsmith

As head of the Justice Department's Office of Legal Counsel, Jack Goldsmith led the team of lawyers that advises the presidency on the limits of executive power. During his tenure, he battled the Bush White House on the now-infamous "torture memos," as well as on issues of surveillance and the detention and trial of suspected terrorists. Goldsmith resigned his post after nine months.

Recent controversies such as Google's business in China and the U.S. government's role in policing eBay transactions have put a spotlight on the intersection between governments and the Internet. Legal scholars Jack Goldsmith and Tim Wu address the issue in their new book, Who Controls the Internet? Illusions of a Borderless World.
