If that is their law and she disobeyed their law, she should pay the penalty. Just because she is a professional athlete doesn't give her the right to violate their laws.
As such, she should admit guilt, say she made a mistake, that it was not for distribution but personal use, and ask to be sentenced to time served and deported.
She is homosexual; illegal in Russia as well, I believe. What made her think she would be welcome there???
