What is the author's style in Chain of Command: The Road from 9/11 to Abu Ghraib by Seymour Hersh?

The world of U.S. and world politics is examined, where sound bites, speeches and press releases must be analyzed for what they really mean by examining the actions that follow. The subject of 'spin' is delved into as the Administration puts a positive spin on their actions on the War on Terror, which do not necessarily reflect reality. Statements from politicians range from exaggerations and omissions to outright deception.
