Gary McKinnon — crowned by the Pentagon as the biggest hacker of all time — will have to wait a bit longer before heading to the U.S. to face criminal charges. The European Court of Human Rights will now allow him to stay in Britain until August 28 to review his appeal against extradition. McKinnon has been pleading innocence throughout all this, claiming he was simply curious about what information the U.S. military and NASA had about UFOs. []
