Gary McKinnon is a Scottish systems administrator and hacker who was accused in 2002 of perpetrating the "biggest military computer hack of all time", although McKinnon himself states that he was merely looking for evidence of free energy suppression and a cover-up of UFO activity and other technologies potentially useful to the public. On 16 October 2012, after a series of legal proceedings in Britain, then Home Secretary Theresa May blocked extradition to the United States.
