All competitors know the rules IW is no exception. All she had to do was make a call to the FEI and the suspension could have been avoided.
To me the story of her horse needing this drug for vet treatment sounds just like that - a story.
She has been caught , and is embarking on a PR
exercise to try and save what reputation she has left . If a horse has a cross contamination that can be traced to sloppy barn management that's bad enough - but her horse was DELIBERATLY drugged with what she would have known was a banned substance - she can try to explain all she wants but at the end of the day she knew what she was doing and didn't inform the FEI beforehand , call me a cynic but I've heard stories like this before.
And I believe that a zero tolerance regime is warranted otherwise people like IW would get away with drugging their horses because of who they are , they believe that because they think they are the best they are able to do what they want.
