WikiLeaks: We don't know source of leaked data

LONDON — WikiLeaks' chief said late Tuesday that his organization does not know who sent it some 91,000 secret US military documents, telling journalists that the website is set up to hide the source of its data from those who receive it.
Editor-in-chief Julian Assange said the added layer of secrecy helps protect the site's sources from spy agencies and hostile corporations. He acknowledged that the site's anonymous submissions raised concerns about the authenticity of the material, but said the site has not yet been fooled by a bogus document.
Assange made the claim in a lengthy hour talk before London's Frontline Club, in which he outlined the workings of WikiLeaks and defended its mission.
