The Real, Terrifying Reason Why British Authorities Detained David Miranda 

The scariest explanation of all? That the NSA and GCHQ are just showing they don't want to be messed with.

Last Sunday, David Miranda was detained while changing planes at London Heathrow Airport by British authorities for nine hours under a controversial British law -- the maximum time allowable without making an arrest. There has been much made of the fact that he's the partner of Glenn Greenwald, the Guardian reporter whom Edward Snowden trusted with many of his NSA documents and the most prolific reporter of the surveillance abuses disclosed in those documents. There's less discussion of what I feel was the real reason for Miranda's detention. He was ferrying documents between Greenwald and Laura Poitras, a filmmaker and his co-reporter on Snowden and his information. These document were on several USB memory sticks he had with him. He had already carried documents from Greenwald in Rio de Janeiro to Poitras in Berlin, and was on his way back with different documents when he was detained.
