“We are concerned about the unlawful way in which these powers were used and the chilling effect this will have on freedom of expression,” said Kate Goold, a lawyer with the firm representing Miranda.
Miranda was detained by police at Heathrow Airport in London as he was about to fly home to Brazil, where he lives with Greenwald. UK police detained him for nearly nine hours, the maximum amount of time allowed by a provision of the UK’s Terrorism Act known as Section 7.
Miranda’s partner, Greenwald, is responsible for breaking the story of domestic surveillance programs carried out by the U.S. National Security Agency as well as the UK’s Government Communications Headquarters. He broke the story after being supplied with classified material by former contractor Edward Snowden.
