If the Russian swimmer was cheating she should have called her out. The olympics are built upon a history of honesty and trust. If there is cheating in the Olympics that this integrity has been destroyed and it destroys the creditbility and entire system upon which the olymics is built.
Lilly King was right for calling out the Russian swimmer for cheating. King is an Olympic swimmer, and it would not have been fair to her, or others that are honestly competing without the use of banned substances. It also taints the sport and the entire Olympics that she earnestly participates in.
Yes, if the Russian Swimmer cheated, Lilly King should have called out the swimmer for cheating. It is disheartening to other athletes for one of the athletes in the competition to get away with cheating. This is not fair and you cannot expect someone who knows that cheating took place to stay quiet about it.
Russia was recently implicated in a doping scandal where it was revealed that there was a state-sponsored system for athletes to use performance-enhancing drugs in various competitions. The Russian swimmer should definitely have been exposed by Lilly King - it is high time to end steroid use and cheating in athletic events.
