There are dumb ass horse trainers all over the world
I found this video on Youtube (where else do all the dummies posts themselves?) that shows a horse in training during it's first ride. The horse, trainer and rider are all in Hungry, at least that is the language I hear being spoken. I won't put the video on here because for some odd reason they don't know how to post a video with it right side up! So tilt your head or if you have a laptop sit it up on end to watch. The trainer has the horse on a lunge line with rider on board, of course without a helmet on a less than green broke horse. The rider has absolutely no control, not even reins to help control the horse should it spook. Of course there is an accident and the rider notes she has scars from it. Blame that one on an inept trainer that has full disregard for the safety of the people working with him.
