New technology always brings new means of expression and dissent. From the printing-press-driven Protestant Reformation to last summer’s Iranian rebellion “broadcast” on Twitter and Facebook, rebels often find new ways to get the word out.

In the early 1970s, a disgruntled military veteran, scholar and war planner used a Xerox machine to make a point and inadvertently toppled the U.S. government.

“P.O.V.” (9 p.m., PBS, check local listings) concludes its 23rd season with the 2009 documentary “The Most Dangerous Man in America: Daniel Ellsberg and the Pentagon Papers” by filmmakers Judith Ehrlich and Rick Goldsmith.

“Dangerous” recalls Ellsberg’s time in the Marines and his eagerness to engage in combat even after leaving the service and becoming a civilian analyst. In a series of interviews, he explains his increasing disillusionment with the war and disenchantment with leaders who expressed grave doubts about Vietnam in private and then offered the public a rosy litany of lies.

After Ellsberg’s boss, Secretary of Defense Robert McNamara, commissioned a 7,000-page history of the war, Ellsberg became convinced that it should be made known to the public. His decision to steal, copy and leak the secret history known as “The Pentagon Papers” resulted in one of the greatest crises in government’s relationship to the press and ended with a landmark Supreme Court decision. And the Nixon administration’s efforts to prosecute and personally destroy Ellsberg led to the excesses that would become known as Watergate.
