Olympian fears

It seems like fear drives the Olympics these days as much as 'citius, altius, fortius'. The Greeks are, apparently, spending up to €1 billion on security for the Athens games. And fear of a screwed-up planet seems to be a major factor behind bid criteria for future games. For example, Sydney made a major play of reclaiming land affected by toxic waste. I'm sure London will too.

But what about just organising a decent event?
