July 2013, Prime Minister David Cameron sent Jeremy Heywood, the Cabinet Secretary, to meet with Alan Rusbridger, editor of The Guardian. Accordingly, Heywood ordered the editor to cease publishing articles based on the Snowden disclosures. According to The Guardian, Heywood said: "We can do this nicely or we can go to law", adding that "A lot of people in government think you should be closed down". On July 20, the destruction of computer hard-drives was carried out by several Guardian staff members under the observation of experts from GCHQ. The Guardian said the authorities were told of the existence of multiple copies of the data outside the UK. The deputy editor, Paul Johnson, who was involved in the destruction told Luke Harding about the experience. "It was purely a symbolic act", Johnson said. "We knew that. GCHQ knew that. And the government knew that. It was the most surreal event I have witnessed in British journalism". Arrest of David Miranda In August 2013, the Metropolitan Police detained Greenwald's partner David Miranda at London's Heathrow Airport under Schedule 7 of the Terrorism Act 2000, while he was traveling home from Berlin. A February 2014 court decision upheld the detention as appropriate. Greenwald described his partner's detention as "clearly intended to send a message of intimidation to those of us who have been reporting on the NSA and GCHQ". Miranda was detained for nine hours and his laptop and other items were seized. He has since sued the Metropolitan Police for misuse of their powers. According to The Guardian, the claim "challenging controversial powers used under schedule 7 to the Terrorism Act 2000, maintains that Miranda was not involved in terrorism and says his right to freedom of expression was curtailed". In December 2013, Greenwald and Miranda openly advocated for asylum in Brazil for Edward Snowden in exchange for the fugitive leaker's cooperation in investigating the NSA. Brazil responded by saying that it was not interested in investigating the NSA. Julian Assange and WikiLeaks In 2006 Wikileaks was created by Julian Assange and the goal for Wikileaks is to capture the truth by any means, which has put them in the International Spotlight over the years. Since its birth, Wikileaks has released classified documents regarding the war effort in the Middle East, documents regarding the detainees in Guantanamo Bay, and releasing emails from Democratic National Committee staffers.
