Well, I've had a good bitch about the whaling of horses where no whip penalties have been applied, because not only is that sometimes the wrong sort of memory a horse will have of his race (and might RO or RR in future, rather than undergo that treatment again, thank you), but it signals to various animal welfare supporters that it's fine for horses to get battered in public. Let's face it, if you saw a man in the street slashing his horse 10, 12, 13 times, you'd probably take the whip off him and give him a taste of his own.
Everything you say about the penalties being too flimsy is perfectly right, as is the reasoning as to why jocks will chance the odd day off. We've sadly had this discussion in the past about punishment not being enough for rough riding, intimidation of other horses, careless barging or cutting up, and nothing has been addressed by either the Irish or the British bodies, other than I think the British are tougher on the whip.
Mr Lyons is not wrong in his complaint, but it's not just the Curragh where there's mayhem. But it needs trainers to decide enough's enough of losing races where morally theirs is the victor, and to demand that penalties are made to count. If the Trainers' Federations or owners' associations won't take a stand, then there'll be anomalies galore in the future, to no-one's benefit - neither horse, punter, trainer, or owner. The jockey will not give a flying fandango when he's taking 10% of a good prize home, as you say, and will be remorseless about causing interference.
If you're on the Irish owners' committee, Cantoris, this would seem to be an apt time to raise the matter, as it's becoming a regular occurrence.
