It’s good that USEF corrected its rules to include out of competition abuse within its sanctionable offenses. The FEI has had that option in the past and has used it, but USEF doesn’t seem to have had the legal wherewithal until now. Hopefully A.M. will have his comeuppance if they find him responsible.
Nothing can stop the abuse of horses in the U.S. in backyard barns or schooling shows. I don’t know who she is, but if the woman shown in that link isn’t competing in USEF or FEI shows, nothing can be done about it.
Abusive riding, drugging horses, and the riding of lame horses by people (not necessarily purposefully but by people who don’t know what they don’t know, and don’t seem have a qualified person on the ground to let them know their horse is NQR) are unaddressed issues that can’t be solved by USEF.
At a schooling show where there are no rules, there is no accountability.
There is no keeping Safe Sport banned sex offenders from the schooling show grounds, nor the people banned or suspended by USEF or the FEI for abusing horses, or for medication violations from competing in the “fun” schooling show.
I remember the schooling shows put on by our riding club fondly, but they went under AHSA rules and no one would have dared to cheat. They were the essence of a schooling show, fun and schooling. No one was there to win.
What I have seen of schooling shows recently was not that. 
It’s too bad that we don’t require “trainer” credentials in the U.S. as does BE and the German system. In that case the trainer credentials could be removed as part of the sanctions and put abusers out of business, though I guess that NFs everywhere hesitate to do that for legal reasons.
It’s good though, to see the advent of horse welfare rules in U.S.
TB racing, with the HISA rules, and USEF along with the FEI becoming more serious about setting down members for horse welfare issues, in and outside of competition, are welcome and a long time coming.
I wonder how much the time needed to verify the date, time, and place of photos and videos slow down the investigations. With the advent of AI, photoshop etc…it must be a lengthy process to verify, and expensive to boot.
I hope that the people stepping up, and our NF cracking down, will result in people, whether in the National or local USEF levels, being held accountable for their actions.
