We don't know who to hold responsible for such an issue.
Now I have to admit I hardly believe Sheikh Mohammed wasn't aware of what is going on..... Which makes me sad to say, because if such information is disclosed it will for sure affect directly or indirectly Sheikh Mohammed's public image.
We don't know who is behind all this .For this reason, it is better to abstain from making judgements that are too hasty.
Fairplay and honesty give mean and value to the Victory and the lurking temptation to cheat is sooner or later sanctioned. I remember reading that , few years ago, Sheikh Hamdan's Horse has failed a doping case and was banned from racing for few months...
However more evidence may also be collected to help shed more light on the whole issue.
I hope the Authorities response assists in clarifying this matter.
