Oxford University Press published Chesterman's twelfth book in March 2011.

Cole said that Chesterman "argues convincingly that the specter of catastrophic terrorist attacks creates extraordinary pressure for intrusive monitoring; that technological advances have made the collection and analysis of vast amounts of previously private information entirely feasible; and that in a culture transformed by social media, in which citizens are increasingly willing to broadcast their innermost thoughts and acts, privacy may already be as outmoded as chivalry.""New York Review of Books", 22 December 2011 .
