The man who leaked the Pentagon Papers on the Vietnam war in 1971, Daniel Ellsberg, has given his backing to Wikileaks.Speaking to BBC World Service, Mr Ellsberg disagreed with US Secretary of State Hillary Clinton's statement that the latest leaks could endanger lives."That's a script that they role out every time there's a leak of any sort," he said.It is not leaks, but "silences and lies" that put peoples' lives in danger, he believes.
