I'll start by saying that the legal system has let down sport as well. The legal system has particularly let gymnastics down. Even recently, we have had multiple coaches let off, stays of proceedings and acquittals, and that's if we can get enough evidence and enough brave witnesses to come forward to even take a complaint all the way through the legal process, and that's about one out of a thousand. If the legal system lets us down, then that person doesn't have a criminal record to be checked with the background check.
What we also are dealing with are hundreds of coaches who are indoctrinated with the mentality that to produce an athlete, you must use harsh techniques, you must shame them, you must guilt them and you must physically manipulate their bodies into positions, despite the pain or injury it causes. There's no registry for that, and there are no criminal charges for that. Children can be brutalized.
My colleague Amelia was overstretched in splits with her leg above her head by her male coach, who snapped her hamstring off her pelvis, and it took a piece of bone with it. There's no registry for that. We don't protect our children beyond the family. If a parent puts a cigarette burn on a child, they'll be called to task, but a coach who physically damages a child is not held to the same account.
