Last summer ... I spent three days in Moscow hanging out with Edward Snowden for a Wired cover story. He told me that what finally drove him to leave his country and become a whistleblower was his conviction that the National Security Agency was conducting illegal surveillance on every American. Thursday, the Second Circuit Court of Appeals in New York ... ruled that the NSA program that secretly intercepts the telephone metadata of every American - who calls whom and when - was illegal. It's now up to Congress to vote on whether or not to modify the law ... by June 1, when they need to reauthorize the Patriot Act. A PEW survey in March revealed that 52 percent of the public is now concerned about government surveillance, while 46 percent is not. There is now a sort of acceptance of highly intrusive surveillance as the new normal, [while] the American public [remains] unaware of many of the agency's long list of abuses. It is little wonder that only slightly more than half the public is concerned. For that reason, I agree with Frederick A. O. Schwartz Jr., the former chief counsel of the Church Committee, which conducted a yearlong probe into intelligence abuses in the mid-1970s, that we need a similarly thorough ... investigation today. "Now it is time for a new committee to examine our secret government closely again," he wrote in a recent Nation magazine article, "particularly for its actions in the post-9/11 period."
