They already do this in Canada, but in reality they never actually pull anyone off.
There are some really interesting points, one being how they see public funding going towards High Performance only might have an effect on the ability to run events as safely as possible because of lack of volunteers and support etc.
Another interesting point, is where it mentions that the course should always err on the side of the fence not creating any additional risk if it doesn’t have to. Like ground rails, and that if they can be used to make the fence safer, they should be used. I hope course designers heed this advice. Not sure why they are so against ground rails. Ground rails aren’t going to make a horse jump or not jump but they will certainly improve the horses chances of jumping the fence safely.
