Earlier quoted context omitted.
The thing is... who else would decide? Isn't it the function of the state to make decisions based on information that is not available to the general public?
No-one. No-one would decide. It's not a decision that needs to be made. Any history of sexual abuse -> be put on a register that prohibits ever working with children again.
So your answer appears to be that the state decides, since they decide what constitutes sexual abuse.
