Radley, Radley... Please. This isn't the "British Olympic soccer team" giving the Nazi salute in 1938, it's the English soccer team. You may think this a minor matter, but I assure you it makes all the difference in the world.
But yes, it's rotten that the British Olympic Association should be wanting to gag athletes who might - albeit improbably - feel like protesting China's, er, mixed human rights record from doing so.
