I'm disappointed in how Greenwald planned the whole thing. Did he really not expect this to happen - especially in UK? Why didn't he have Miranda delete the files as soon as he gave them to Laura Poitras or whatever he did with them in Germany.
Now, whatever Greenwald wants to release next needs to be done fast, before the governments prepare well crafted rebuttals to whatever he's releasing, because they'll know what he'll release next.
