Book excerpt: An eye-opening look at how the top media covers world news. Explores the pack mentality that drives reporters and how it distorts what we know about global news, economics, wars, human rights and more. Vividly illustrated with incisive anecdotes, it argues that while individual reporting is at its peak, the system is less reliable than ever. Analyzes coverage of recent hot spots such as Iran, Somalia and Eastern Europe. Features interviews with media stars.
