Have we seen a news report yet about how Snowden traveled to Hong Kong? His choice of destination may have been dictated by where he could fly on a nonstop airline flight from Hawaii, where he was last based. His travel documents, because he was contracting for the NSA, may already have had restrictions on which destinations he could fly to. (Such restrictions have been routine for NSA employees for more than a generation. Airlines check travel documents before you board a plane on an international flight, because the airline is responsible for returning you at no charge to you if you are denied entry for lack of proper travel documents at the border of your destination.) He may simply have had no better choice when he had opportunity to leave work and leave home.
