Now both Poitras and Greenwald are afraid to go back to US, though. I wonder why would they avoid the most journalist-friendly country on Earth?
They both live outside of US now and have mentioned their reasons countless times. Laura Poitras explained why she's staying in Germany and how she does not take any materials with her during her trips to US, for example, at the last CCC: https://www.youtube.com/watch?v=ZmKqdMDastM
Now you'll say that location of Guantanamo Bay prison outside of US jurisdiction is an 'unfortunate accident' as well. Both seem quite purposeful decisions to me.
And yes, the fact that two probably most important journalists of modern times have both chosen to go into exile just to do their job, even though both love their country, - I think this actually says quite a bit about the freedom of press in the said country.
Others have already mentioned that they don't carry their work into the US, but they, themselves, still travel to the US. This is hardly the "exile" that you want it to be (to prove your point).
Poitras's and Greenwald's behavior support a conclusion that they are not afraid to go back to the U.S.
Your statement still fails to refute any of my assertions.
