I read that Sun Yang was confronted by people who claimed they were officials to take blood samples from him. Apparently they took the samples but afterwards Sun broke the vials smashing them to the ground when it was suspected they were not officials but from the Western media. That was used to say it was an admission of guilt on Sun Yang's part for destroying the vials. I never read anything that said there were officials authorized to take blood samples. What makes them think they wouldn't taint the samples in a "Gotcha!" moment? If it was the media it would be a tabloid news entity that wouldn't care for the truth and fabricate it to make a better story. Western countries are perfectly okay with this deception. If it were the other way around, they wouldn't accept that and be outraged and there probably would've been violence involved if it were one of their athletes in a roid rage moment.
