If you're interested in learning more about media manipulation, I highly recommend reading the book Trust Me, I'm Lying [1]. It's shocking how easy it is to sway public opinion or plant fake stories that could have a national impact.
If you want a specific example, just read about Nayirah's testimony. How the Bush government, Kuwaiti diplomats and a well placed PR firm along with collusion by news/media used an outright lie to sway the public into supporting war. Nobody was prosecuted for this, nobody went to jail.
If you want a second example, go read about the yellowcake propaganda based on forged documents, by once again a bush government and well placed PR firms along with collusion by news/media to use another outright lie to sway the public into supporting war. Nobody was prosecuted for this, nobody went to jail.
As George likes to say "Fool me once..."
"The first casualty in war is the truth".
