A British court has dismissed a challenge brought by David Miranda, the partner of journalist Glenn Greenwald who was detained and questioned under anti-terrorism laws for nearly nine hours last year at Londons Heathrow Airport. Miranda was flying from Berlin to Brazil at the time of his detainment, and was carrying devices containing 58,000 documents from the National Security Agency (NSA) and Britains Government Communications Headquarters (GCHQ). Authorities confiscated the documents and Mirandas equipment, in what Greenwald later described as a total abuse of the law, alleging that officials used the anti-terror law as a way to seize journalistic documents. Greenwald, a former journalist for the Guardian, has been publishing revealing stories about the NSA based on documents provided by former US government contractor Edward Snowden.
