Well, for me it is very strange to dont see ANY American doping case in this Olympics Games and in general........the same with the retroactive dopings of Beijing and London, we can see many Russians (i dont say they dont use drugs but im sure they are not alone), and now we have this information about the TUEs and, oh casualty, U.S.A have more than any other country........
Please, don try to defend this, there are so many casualitys to dont think there are some parciality, of course for political/economical reasons.
