I don't think you can call that rollkur. The horses mouth is closed and there is no pressure on the reins or on the horses mouth. I don't like how the horse is so over bent but I'm not a reiner. As far as loping his horse for 40 whole minutes without a rest being cruel, I must be the horse worlds version of Hitler because I ride my horses on hot or cold or rainy days for several hours without much of a break. They are conditioned and fed well (as I'm sure Clintons are ) but they have a job to do and we often can't stop until it is done.
Perhaps if you are looking at Mindy and seeing the kind of horse you would like to have you shouldn't be so quick to critisize how she came to be that horse.
The horse in the pics wasnt Mindy looked to me like Diez either way I like him and his horses look extremely well cared for after all they are used to the Texas heat. Sometimes people need to realize some horses have a job that means they do more than sit in a stall or pasture all day.
