Natalie Haynes: The Games provide their own security...

Given the large number of judokas, wrestlers and boxers in this year's Olympics, any miscreant will be flattened before they can do any real harm

The battle to be my favourite Olympian is intensifying. For a couple of days, it was Alan Campbell, the bronze medal-winning rower. Anyone who has to be physically lifted out of a boat, unable to speak or walk, has achieved a level of effort that transcends achievement.

But now there's also Edith Bosch, the world judo champion from Holland who took on the drunk guy who apparently threw a bottle onto the track just before the men's 100m final. And beat him, by her account.

After all our fears about security at the Games, it turns out we didn't need to worry.

Given the large number of judokas, wrestlers and boxers in this year's Olympics, any miscreant will be flattened before they can do any real harm.

There was something peculiar about the medal ceremony at Wimbledon on Sunday. At first, I thought it was the welcome sight of Andy Murray smiling. Then I realised it was Roger Federer in his Swiss Team tracksuit. It must be the cheapest outfit he has ever worn. His critics have scoffed at his fondness for custom-made kit with his initials sewn onto it in gold, but it's one of the things I love about him. I hope he's back in designer clothes for the US Open, or I shall have to write in to Vogue and ask them to stage an intervention.

Ben Ainslie seems a decent chap and, like all great athletes, is far less excited by his victories than anyone interviewing him. He remained completely calm as the BBC's interviewer reached a pitch so high that any bats in Weymouth must have been flying off-course. Also, the BBC keeps showing him in post-race, mid-event fury, declaring that his Danish rival "didn't want to make me angry". I love how this makes him sound exactly like Dr Bruce Banner. Hulk sail.

To the delight of many, Oscar Pistorius has competed in this year's Olympics, an astonishing achievement for a man born without fibulas. To the delight of a few, he has failed to qualify for the 400m final. The disabled-bashing that he has endured is breathtakingly unpleasant: he should know his place, it seems, and stay in the Paralympics where he belongs. It's bigotry, dressed up as something else.
