This isn't a freedom of speech issue. I'm not annoyed by the fact that he said something in public: if he had been down at the local train station and pulled out a bullhorn and started yelling that he hates Bush and wishes Bush was dead, that's a different matter.
What I didn't like is the fact that this dude used his position as an Olympic athlete to make a statement to the effect that if he wasn't in the Games he would be at home shooting Americans, the same Americans that have facilitated his appearance and safe return from the Games.
Do you see the difference? It's more of an issue about the context in which he said it, not the plain fact that he said it alone.
