IMHO, bad call by the AG. What Snowden did could very easily cause US deaths if not immediately then sometime down the road. I see no fundamental difference between him and Julius and Ethel Rosenburg, the two WWII traitors who compromised the atomic bomb to the Soviets and were later tried, convicted, and executed. How would the AG conceivably explain guaranteeing Snowden's life to the loved ones of some future casualty of his treachery? A lot of people have spent a lot of their lives, and some have lost their lives, protecting classified information. This makes a mockery of all that.)
