Here's the main problem. When a young person or their family files a complaint, there will often have been no overt physical violence. In fact, it's very rare. Emotional blackmail often involves a bond of trust or love. There are also the bonds forged when parents have blind faith in the coach.
We really need to better understand, through science, what leads to the act being committed. The climate that develops over several years gives certain aggressors the opportunity to progress to actions, whether it's during a tournament or a trip abroad. In my opinion, it's essential to call a spade a spade. Current laws don't always allow charges to be laid, since the person in the position of authority will sometimes wait until the young person has reached the age of majority before acting. There's a perversion in all this that hasn't yet been considered. It's a huge blind spot.
