The Guardian's Sound of Silence
Remember when the AP ran the bogus story about the Crowd booing when President Bush annonunced that Bill Clinton was ill? There was no booing and the report created a firestorm in the blogsphere. Faced with an onslaught from bloggers, the AP was forced to retract the story.
The Guardian's Jonathan Freeland was caught in the reverse when he claimed there was no applause in response to this statement by PM Blair at the Labor Party conference:
"So when Blair said that a withdrawal from Iraq or Afghanistan would be "a craven act of surrender", he said it to silence."
Once again, bloggers exposed the fakery. Here's a recording of Blair's statement and the resulting applause.
The Guardian was forced to correct the story.
