The New York Times exposes one of their own below. Having read the full article, still having a bit of difficulty understanding why the paper of record didn’t catch Jayson Blair’s deceptive practices earlier.

CORRECTING THE RECORD
Times Reporter Who Resigned Leaves Long Trail of Deception
May 11 2003
A staff reporter for The New York Times committed frequent acts of journalistic fraud while covering significant news events in recent months, an investigation by Times journalists has found. The widespread fabrication and plagiarism represent a profound betrayal of trust and a low point in the 152-year history of the newspaper.
The reporter, Jayson Blair, 27, misled readers and Times colleagues with dispatches that purported to be from Maryland, Texas and other states, when often he was far away, in New York. He fabricated comments. He concocted scenes. He lifted material from other newspapers and wire services. He selected details from photographs to create the impression he had been somewhere or seen someone, when he had not.
And he used these techniques to write falsely about emotionally charged moments in recent history, from the deadly sniper attacks in suburban Washington to the anguish of families grieving for loved ones killed in Iraq.
In an inquiry focused on correcting the record and explaining how such fraud could have been sustained within the ranks of The Times, the Times journalists have so far uncovered new problems in at least 36 of the 73 articles Mr. Blair wrote since he started getting national reporting assignments late last October. In the final months the audacity of the deceptions grew by the week, suggesting the work of a troubled young man veering toward professional self-destruction.
Mr. Blair, who has resigned from the paper, was a reporter at The Times for nearly four years, and he was prolific. Spot checks of the more than 600 articles he wrote before October have found other apparent fabrications, and that inquiry continues. The Times is asking readers to report any additional falsehoods in Mr. Blair’s work; the e-mail address is retrace@nytimes.com.
