But that's the beauty of forums like this - we don't have to be riders or even 'insiders'. We could use the whip as any analogy for any situation where someone obtains a pecuniary advantage (she says in best constable-speak) by breaking the rules, so we don't have to be qualified to discuss what is really a matter of ethics as much as rules 'n' regulations.
Suppose I give my horse a course of treatment and forget to write it down in my medications book, my horse wins, my mistake gets found out. What a hullabaloo follows! Press coverage: Day of Shame, Racing is Still Bent, and so on. I pay a monster fine, I might lose my licence, and I'll always have 'that' hanging over my head until I die. I've made a mistake - I wasn't intending to misrepresent what I'd done, I'm terribly sorry, sackcloth and ashes. No, not enough - you will pay a huge price.
Jockey, on the other hand, eyeballing 10% of a huge first prize (doesn't matter which race or where), smashes into his horse and breaks the rules in doing so. Horse wins. Everyone's happy, he trousers enough to buy a new Merc and more, nobody loses their livelihood, nobody gets a monster fine, nobody has a stigma attached to them forever. Loses less than a week's work, which would've been teeth-picking money, anyway, considering what he's got for this.
Which rules when broken bring racing into disrepute? Administering, say, a cough medicine which you fail to note - or publicly beating-up a horse, for thousands, if not millions, to see? Jockeys are never, ever told they've brought the sport into disrepute if they over-whip a horse. Why? Why is one issue a heinous crime, worthy of hanging and quartering, and the other (which involves the side issue of welfare) barely breaks a sentence in the RP, so inured have we all become to regular whip bans.
