“Whatever one thinks of Mr. Assange, he is a skilled data security expert. He knows an awful lot more about information security than even the most tech-savvy journalist. His platform appears to have worked: none of WikiLeaks’s confidential sources have ever been exposed by the organization. (Bradley E. Manning, the detained Army private who has been accused of the leak, was exposed by an acquaintance.) Until journalists take their security obligations seriously, it will be safer to leak something to WikiLeaks — or groups like it — than to the mainstream press.”
