Why Associated Press was right to sever ties with Narciso Contreras; Guardian, 1/23/14

Roger Tooth, Guardian; Why Associated Press was right to sever ties with Narciso Contreras:

"Except that the major wire agencies and their clients rely on their images being totally authentic; that's why news organisations like the Guardian spend many thousand of pounds each year on their contracts. In a news environment it's all about a chain of trust: from the photographers through to the agencies, newspapers and websites, and then to the readers. If that chain is broken, any picture could be suspect, and that can't be allowed to happen."
