As a dressage judge (very junior in status, senior in experience), I am disturbed at what I see in the arena. I recently scribed for the whole FEI series of classes in a CDI***. Three horses stood on their hind legs, not just a "levade" position but absolutely vertical. Riders seemed unaware they were split seconds from death or serious injury from being crushed by a horse falling over backwards. I had seen some warmups of these horses in rollkur during breaks in the competition. Many of the FEI horses were warmed up in rollkur and not all of them reared, but having three FEI level horse do so during their tests in one show I had never seen before.
