Download or read book NSA Secrets written by The Washington Post and published by Diversion Books. This book was released on 2013-12-17 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pulitzer Prize–winning investigation into surveillance abuses and the Edward Snowden case that brought them to light. The NSA's extensive surveillance program has led Americans to question threats to their privacy. As reported by the Washington Post, in their Pulitzer Prize-winning coverage of whistleblower Edward Snowden's NSA leaks, NSA Secrets delves into the shadowy world of information gathering, exposing how data about you is being collected every day. From his earliest encrypted exchanges with reporters, Edward Snowden knew he was a man in danger. Sitting on a mountain of incriminating evidence about the NSA surveillance programs, Snowden was prepared to risk his freedom, and his very life, to let the world know about the perceived overreach of the NSA and the massive collection of personal information that was carried out in the name of national security by the U.S. government. The Washington Post’s complete coverage of the NSA spying scandal, which it helped break, is now collected in one place to give as comprehensive a view of the story as is known. From the first contact with Snowden to the latest revelations in worldwide cellphone tracking, the award-winning reporters at the Post have vigorously reported on the scope of the NSA’s surveillance. Snowden called the internet “a TV that watches you,” and accused the government of “abusing [it] in secret to extend their powers beyond what is necessary and appropriate.” Here, the secrets of those who tried in vain to remain in the shadows are revealed.

Download or read book Pearl s Secret written by Neil Henry and published by Univ of California Press. This book was released on 2002-09 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pearl's Secret is a remarkable autobiography and family story that combines elements of history, investigative reporting, and personal narrative in a riveting, true-to-life mystery. In it, Neil Henry—a black professor of journalism and former award-winning correspondent for the Washington Post—sets out to piece together the murky details of his family's past. His search for the white branch of his family becomes a deeply personal odyssey, one in which Henry deploys all of his journalistic skills to uncover the paper trail that leads to blood relations who have lived for more than a century on the opposite side of the color line. At the same time Henry gives a powerful and vivid account of his black family's rise to success over the twentieth century. Throughout the course of this gripping story the author reflects on the part that racism and racial ignorance have played in his daily life—from his boyhood in largely white Seattle to his current role as a parent and educator in California. The contemporary debate over the significance of Thomas Jefferson's longtime romantic relationship with his slave, Sally Hemings, and recent DNA evidence that points to his role as the father of black descendants, have revealed the importance and volatility of the issue of dual-race legacies in American society. As Henry uncovers the dramatic history of his great-great-grandfather—a white English immigrant who fought as a Confederate officer in the Civil War, found success during Reconstruction as a Louisiana plantation owner, and enjoyed a long love affair with Henry's great-great-grandmother, a freed black slave—he grapples with an unsettling ambivalence about what he is trying to do. His straightforward, honest voice conveys both the pain and the exhilaration that his revelations bring him about himself, his family, and our society. In the book's stunning climax, the author finally meets his white kin, hears their own remarkable story of survival in America, and discovers a great deal about both the sting of racial prejudice as it is woven into the fabric of the nation, and his own proud identity as a teacher, father, and black American.
