We can't afford to get too high-horsey about this. Looks like Sinner has got off a doping rap (or at least reduced the sanction to nothing) by deployment of very expensive lawyers, where lesser (poorer) athletes would have fared worse. Similar to the Froome salbutamol business a few years back.
Money talks, and it doesn't necessarily mean corruption à la Armstrong and the UCI, it's just that good lawyers cost a lot.
It's the rich wot gets the pleasure, it's the poor wot gets the blame. It's the same the ole world over, isn't it a blummin shame?
