I would say in answer to your question re the jiggers, yes, yes, and to the third, not to improve performance, but rather manners. Reason for four, who knows, maybe the fact that there is about 600 horses involved, maybe some spares, could of been package deal. Who cares, very minor stuff thus far. No animal cruelty, no drugging horses, no rigging races, no failing or refusing to co operate, only heaps of hype from the media, and stupid people that believe everything they are served up. This is rapidly turning into a farce, but you can expect this when you have the corrupt Australian Police involved. Clearly a witch hunt.
