Now that Reuters has fired one of its photographers, Adnan Hajj, for doctoring a photo, the news organization must do the responsible thing and investigate all of Hajj’s work that Reuters has sent across the wires. When the New York Times discovered that Jayson Blair had plagiarized and fabricated one story, it didn’t fire Blair, retract that story and leave it at that. It put together a top team of investigative reporters to check into every article Blair wrote for the paper.

Bloggers continue to unearth examples of possible image doctoring. Only a comprehensive accounting of Hajj’s work can restore Reuters’s tattered credibility.
