It reads like a political thriller. An NSA spook, Edward Snowden, meets his conscience, blows the whistle on a massive secret attack on the Fourth Amendment, and is pursued globally by an obsessed president. Spice things up with a bit of character development cross-pollinated with a history lesson. First there’s Darth President. His administration has earned the distinction of invoking the Espionage Act of 1917 (a constitutionally questionable World War One relic) more than all other presidents in the previous 96 years combined—by a factor of two. The Obama administration has charged eight people under the act. All previous administrations have charged three.
