Power Beyond Scrutiny uncovers the forces which distort and limit public debate in the media. From the misuse of politicians' expenses to recent phone hacking scandals, establishment corruption has never been more in the headlines. Yet amidst the din there have been seismic silences.

Justin Schlosberg interrogates these silences - why did a plea bargain which allowed Britain's biggest arms company to escape bribery prosecution go almost entirely unchallenged in television news? Why did journalists routinely endorse the official explanation of how intelligence analyst David Kelly died, whilst ignoring the mounting evidence which undermined it? Why, in 2010, did broadcasters offer an unchallenged platform to critics of Wikileaks but not its supporters?

These are some of the questions and imbalances that Schlosberg seeks to address as he explains the nature of public debate in the digital age. In doing so he uncovers a range of news blockages that are more than just accidents of a fragmented, chaotic mediascape. They are ultimately ideological forces which ensure that contestability and dissent remain within definable limits.
