COULD WADA NOT SAVE THE RIO OLYMPICS ?

The Organisers of the 2016 Rio Olympics fear that the suspension of Russia and perhaps other countries or athletes, could cause huge financial losses for Brazil.  Less visitors would want to come and watch the Olympic Games.  

WADA, the World Anti Doping Agency, produced a report which accused countries and competitors of using "dope" to improve  athletic performances.  This led to the suspension of Russia by the IAAF, the International Association of Athletics Federation. 

If WADA is a capable and respected anti doping authority, which appears to be the case, should it not be THE Agency which should "organise and oversee" every stage of the doping control of all athletes that participate at the 2016 Olympic Games ?  

For the first time, why not impose rigorous tests, shortly before and shortly after all events in RIO, which would prove that all competitors were "clean" before the race as well as the first four "over the line" after the race ? 

Any competitor who refuses or fails to submit himself for any test, should be disqualified immediately, but could appeal at a later date and be perhaps be readmitted as a competitor. 

Would this not guarantee that Russia, or any other country, knowing that the new rules applied to every competitor, would ensure that every Russian competitor was clean ?  Would any "unclean" competitor ever dare to try to compete ?  Why therefore expel Russia from ALL future competitions ?

The real difficulty is organising these tests and then validating them rapidly.  Alas, this duty will remain forever.  Is there any other method, more efficient and more simple, to ensure athletes are not "doped", when they are competing like desperate professionals for monetary gain and for glory ?
