It has been a week since the New York Times and the German TV channel ARD broke the news that 23 Chinese swimmers had tested positive for trace amounts of the banned performance-enhancing drug trimetazidine (TMZ) in the run-up to the last Olympic Games, and public ripples we have seen since are only the visible tip of a wave of feeling running through the sport.
The larger part is below the surface, where there is widespread anger, exasperation and disillusionment at the way the 23 were allowed to compete at the Games anyway after an investigation by their national doping agency, Chinada, found the results were caused by kitchen contamination.
