The Org. itself is responsible for this, they refuse to take on the Moral Duty to do a Criminal Records check, and then appoint known offenders !
Small Clubs and Associations here in the U.K, and of course the larger ones, do this. No one is appointed to a position of Authority and therefore power, who has any kind of Criminal Record.
If the Org's claim that they " do not allow members to be alone with someone...... blah...blah.... it is the parents responsibility ..blah ...blah..." was something that worked they could continue to hide behind that nonsense, but NO IT DOES NOT WORK ! or these things would not keep happening.
I hope another huge Law Suit goes their way over this. Maybe, just maybe, then they would then live up to their Moral Responsibility to make sure the vulnerable members are protected.
