In a sign of the times, the London Summer Olympics will be defended by anti-aircraft guns and surface-to-air missiles... just as they were in Ancient Greece. G4S, the world's largest security company, was to provide 12,000 security personnel, but has so far only managed to come up with 4,000. In another sign of the times, not all of their security personnel speak English. So instead the British government will be deploying 3,000 troops, all of whom hopefully do speak English.
