Yes, this is the problem. The Watchtower keeps saying that they contact the authorities when the law requires it, but why do they need a law in order to do the right thing? They can say they hate child abuse all they want, but their actions say they value themselves and pedophiles more than they value victims.
What also bugs me is that elders had knowledge that allowed them to protect their children, but did nothing to protect other children in the congregation. For example, if a person known to have molested children has children themselves, what if they invite another child to spend the night? The elder is going to say no, because why would they risk their child being molested, but other parents would have no way of knowing about it, so they cannot protect their children.
