It sounds like nothing has changed. He always seemed angry, aggressive, and short tempered.
He shouted at an elderly woman named Gloria, who paid him for a lesson and he told her she was wrong, when she instinctively did the right thing while riding the horse Sundust. It was a disgusting, inexcusable display of ignorance and hubris on his part.
I don’t understand why people don’t research if they might have any niggling of a doubt or a question about an online “trainer” who has no record or references. Just do due diligence. Unfortunately, some of the “trainers” who have no show records or any other references and are selling their services, have criminal records related to fraud and/or theft. Some with Olympic chops have brushed with the law as well, but at least they are able teach and ride.
References from a trainer’s instructors or peers from or with whom they have taken lessons, are valuable. If their instructor has a record of producing good riders and good horses, that’s a reference. Competition records are also helpful, but if you, as a “trainer”, have no competition record (unusual) but have the riding chops and the results of the horses you’ve brought up, as well as good references from your instructors, then call yourself a pro and charge people to ride their horses and to listen to you. It’s the U.S. after all.
It’s strange that people rely on student reviews (testimonials 
) about trainers on the internet. When you hire someone in any other business do you rely only upon reviews from beginners and/or the people that they supervise, or do you want to know what the teacher/trainer’s supervisor thinks of their knowledge and job performance?
While the student’s experience is an important part of the equation, the balance must be had with a reference from the teacher’s teacher. The beginner doesn’t know what they don’t know and thus their “testimonial” (when did that become a term for a reference?) is often worthless.
It was a shame that Buck was able to convince anyone that he knew anything about riding or training horses, especially when the videos proving otherwise were there to be seen, displayed by him on the internet.
