I am not going to read all the wonderful answers so that I can give a gut reaction answer first.
A huge problem in Watchtower is saying that they are in a spiritual paradise and having minors engage in the recruiting work.
Clearly, a suggestion that minors never go in the recruiting work would not fly through the governing body. But certainly, it should be well stated that there are bad elements all around, even in the congregations (weeds among the wheat). And minors should only work with their relatives, no exceptions, no dropping them off to work with others, not even with the elders (really should be especially not with elders).
Mandatory reporting should be followed. When parents won't go to police, elders should explain that mandatory reporting protects other children. Adults that don't want to face this from their past should know that elders still must report for the safety of others. If local law prohibits elders from revealing (alledged) victim names, then they report w/o the names.
If experts interview victims and perpetrators, congregations can disfellowship based on such interviews or court outcomes. They may legally be bound in many jurisdictions not to announce names. They should at least remind the congregation never to leave their child in the care of other congregatoin members without being sure about them.
I know you are trying to push these examples to the point where there is no proper way to "handle" them. There are often difficult situations, but Watchtower rules make matters worse and even start at a problem.
Victims should never have to face the perpetrator under the direction of elders. Any such action with authorities is only done with social experts.
