Police officers walk past the Olympic Stadium, in the Olympic Park, in Stratford, east London, July 17, 2012. The head of G4S admitted his management of the London Olympics staffing scandal had embarrassed the British government and left the world's biggest security firm's reputation in tatters as he fought to save his job on Tuesday. G4S has been at the centre of a political firestorm, and has lost about 650 million pounds ($1 billion) in market value, since it announced it could not provide the promised 10,400 Olympic security guards just two weeks before the Games.
