BEIJING — Five, going on six, years ago, in the weeks before the 2016 Rio Games, an 18-year-old American rhythmic gymnast, Kristen Shaldybin, tested positive for a very low level of a banned diuretic called hydrochlorothiazide, or HCTZ.
The positive test, it was asserted, was due to the levels of HCTZ in the tap water she was drinking straight out of the faucet.
In the years leading up to Rio, Shaldybin was living on Chicago’s upscale North Shore,. Indeed, she is now a graduate of one of Highland Park High, one of the leading schools in the area.
Did the U.S. authorities assert then — as they did this week, amid the furor over 15-year-old Russian skater Kamila Valieva — that the credibility of the entire anti-doping system was at issue?
