Yeah - she broke the law. But she was caught and detained by a corrupt justice system that typically lets people off for minor offenses like drugs for a little cash in the right hands. But that didn't happen in this case due to political reasons.

That's the biggest issue.

Sure, she broke the law. But she isn't being treated like the typical Russian law-breaker from her socio-economic status. Which isn't justice in itself - but it is the expected norm.
