In the general introduction to justice section using Walter Wink's Engaging the Powers we use the image of a loudspeaker to capture something of how the propaganda system around us operates. The propaganda system presents reality in a distorted and biased way.
This distortion happens in very particular ways and one website which tracks these distortions very well is Medialens, a British based media monitoring group. The site is run by two people, David Cromwell and David Edwards, and on a shoestring budget at that, yet they manage to produce an ongoing incisive commentary on how the news is constantly getting distorted in the mainstream media. If you sign up to their 'media alerts' you will get periodic articles with a critiques of topical stories. Well worth a visit.
