History Repeats. "The Most Dangerous Man in America," Daniel Ellsberg addresses Occupy activists.

Once labeled "The most dangerous man in America" Daniel Ellsberg was a former United States military analyst who became the center of a political controversy in 1971, when he released the Pentagon Papers, a top-secret study of U.S. government decision-making in relation to the Vietnam War. Ellsberg has been a lecturer, writer and activist on the dangers of the nuclear era, wrongful U.S. interventions and the urgent need for patriotic whistleblowing.

Here he is seen giving a speech in solidarity with Occupy Wall st activists in the middle of Market street in San Francisco's financial district.
