The IOC should at least investigate the allegations, but only after the American gymnastics federation investigates the allegations first. If there are still complaints after the Americans conduct their own probe, then the IOC should step in. Of course, if there are allegations of sexual abuse, then prosecutors should get involved as well since that belies a criminal act.
Yes, if there is a sexual abuse problem in the USA Gymnastics ranks, the United States should be disciplined. It does not make sense to believe that the United States should escape being disciplined for this type of behavior. It cannot be allowed to continue as it hurts the athletes involved.
No, the United States should not be disciplined for sexual abuse in the USA Gymnastics ranks. An investigation should take place and those responsible for the abuse should be banned from the sport of Gymnastics for life and face criminal charges. This behavior should never be tolerated, but only the appropriate people should be punished.
Unless the International Olympic Committee has established a provision binding participating countries to a "code of conduct," the IOC should stay out of an internal matter. However, to protect young gymnasts - and the image of the U.S. on international grounds - USA Gymnastics officials must take all allegations seriously and remove any coaches and affiliates involved.
