In my experience horses are accident prone to the point of being practically suicidal! I have seen them do grievous bodily harm to themselves on the most benign things! And the saying "Healthy as a horse" WHO MADE THAT UP???? Horses will keel over dead at the drop of a hat.
I can see if a horse owner asked CA "have you ever had a horse die in your program?"
I'm sure he would have had to say yes. Every trainer/barn manager who has had more than a hundred or so horses has probably had a horse die while in their care.
This thing has been blown all out of proportion on all sides, simply because CA has a big name. I'm defending him, and I don't even like his methods all that well
