I'm going tinfoil. Snowden I believe is a marked man. If the Chinese don't spirit him away, he has limited time. No one would buy him, having a sudden heart attack, falling from a balcony, drowning in a bathtub, catching a cold/flu, getting into a car accident. Nope not going to buy it. I think our latest leaker of government secrets will be flying on a plane and the plane will mysteriously explode/crash taking all those on board with him. It will be a maintenance issue.
