Athletes governed by the WADA code are held to a strict standard in doping cases. It doesn't matter how a prohibited substance got into your body. If it's there, you have to take responsibility for it. That has resulted in harsh punishments for some relatively minor or inadvertent offenses. By the same standard, it shouldn't matter how HGH got into Odesnik's hands. He admitted in a court of law that it was there. That should have constituted due process, and he shouldn't have been playing last week.
Update: Another piece from Ford. Looks like she is going to run with this story (thanks Anonymous). Here's an interesting tidbit:
The ITF's anti-doping regulations were introduced as an exhibit in the case, and the two lawyers made opposing arguments about whether the prospect of sanctions from the ITF should be a factor in Odesnik's sentencing. Zeilinga urged the magistrate not to take that into account, calling the ITF's process completely independent. Godbolt asked for leniency, noting the financial impact of Odesnik's potential two-year suspension from tennis.
The guy asks for leniency because he is going to be punished by the ITF already, then fights the case against the ITF. Ah, sincerity...
