I guess what Im looking for is a Child protective service of sports. Does that non profit exist? Is there someone kids could go to outside of the governing organization that would get lawyers involved so fast your head will spin and sue every single person complicit? Because it isnt just Nassar. Coaches all over the nation are violating Safesport conduct every single day of the week and it's enough. We dont let our teachers groom and use predatory behaviors, shaming, hazing, etc at our schools, why in the heck are we paying for it in sports? If the USA Gymnastics association will not protect our children, we must.
I, personally, took the safesport course last night. So there is no reason every single coach in america shouldnt have taken it by now. If they havent even made that happen, it's beyond the time of parental action and involvement.

Not sure if they help with the extent you are talking about though.
