Daniel Ellsberg, a military analyst who leaked what came to be known as the Pentagon Papers, died on Friday at the age of 92. The cause was pancreatic cancer. The New York Times reports: The disclosure of the Pentagon Papers -- 7,000 government pages of damning revelations about deceptions by successive presidents who exceeded their authority, bypassed Congress and misled the American people -- plunged a nation that was already wounded and divided by the war deeper into angry controversy. It led to illegal countermeasures by the White House to discredit Mr. Ellsberg, halt leaks of government information and attack perceived political enemies, forming a constellation of crimes known as the Watergate scandal that led to the disgrace and resignation of President Richard M. Nixon. And it set up a First Amendment confrontation between the Nixon administration and The New York Times, whose publication of the papers was denounced by the government as an act of espionage that jeopardized national security. The U.S. Supreme Court upheld the freedom of the press. Mr. Ellsberg was charged with espionage, conspiracy and other crimes and tried in federal court in Los Angeles. But on the eve of jury deliberations, the judge threw out the case, citing government misconduct, including illegal wiretapping, a break-in at the office of Mr. Ellsberg's former psychiatrist and an offer by President Nixon to appoint the judge himself as director of the Federal Bureau of Investigation. "The demystification and de-sanctification of the president has begun," Mr. Ellsberg said after being released. "It's like the defrocking of the Wizard of Oz." The story of Daniel Ellsberg in many ways mirrored the American experience in Vietnam, which began in the 1950s as a struggle to contain communism in Indochina and ended in 1975 with humiliating defeat in a corrosive war that killed more than 58,000 Americans and millions of Vietnamese, Cambodians and Laotians. [...] Over the years, Ellsberg was mentioned on Slashdot several times. In late 2000, Ellsberg was mentioned in a story about Clinton's veto of what would have been a new law to prevent leaks of classified information. Ellsberg also expressed his support for WikiLeaks founder Julian Assange in 2010 and called Edward Snowden the "greatest patriot whistleblower of our time." He was also featured in a Slashdot story for his view on the growing role of internet companies in the public sphere. In 2011, Ellsberg said companies such as Google, Facebook, and Twitter need to take a stand and push back on excessive requests for personal data.
