Until the punishment affects a trainer's (or owner's) pocketbook, there will be no change. The USEF has never had any backbone when it comes to enforcement and punishment. And, the mamby-pamby interview with the USEF powers that be by the NYT just proves the point. The USEF will spend 5+ years "thinking" about it, another 5 years getting feedback, a couple of years coming up with a policy, then another year to implement it.
Put your freakin' money where your mouth is, USEF. Make the punishment (and fines) so severe that you discourage the behavior. Otherwise, just shut your mouth and get off the pot.
This whole issue is about money. Money is the USEF's favorite pastime. I'm not holding my breath that policy will change anytime soon.
