On June 13th, a fifty-four-year-old former government employee named Thomas Drake is scheduled to appear in a courtroom in Baltimore, where he will face some of the gravest charges that can be brought against an American citizen. A former senior executive at the National Security Agency, the government’s electronic-espionage service, he is accused, in essence, of being an enemy of the state. According to a ten-count indictment delivered against him in April, 2010, Drake violated the Espionage Act—the 1917 statute that was used to convict Aldrich Ames, the C.I.A. officer who, in the eighties and nineties, sold U.S. intelligence to the K.G.B., enabling the Kremlin to assassinate informants. In 2007, the indictment says, Drake willfully retained top-secret defense documents that he had sworn an oath to protect, sneaking them out of the intelligence agency’s headquarters, at Fort Meade, Maryland, and taking them home, for the purpose of “unauthorized disclosure.” The aim of this scheme, the indictment says, was to leak government secrets to an unnamed newspaper reporter, who is identifiable as Siobhan Gorman, of the Baltimore Sun. Gorman wrote a prize-winning series of articles for the Sun about financial waste, bureaucratic dysfunction, and dubious legal practices in N.S.A. counterterrorism programs. Drake is also charged with obstructing justice and lying to federal law-enforcement agents. If he is convicted on all counts, he could receive a prison term of thirty-five years.
