While I appreciate the nod to Muhammed Ali's great moral courage and strength of conviction, I'm not sure that the comparison is exactly apt. The stakes are much higher for Snowden and the playing field is not exactly level. In a period of history where the U.S. routinely practices extra judicial murder, and while it maintains at Guantanamo a prison that exists in a legal black hole and while the U.S. presidency is about to be assumed by a lunatic, I think it is perfectly reasonable for Snowden to take a pass on a date with U.S. "justice."
