The WT takes child abuse more seriously when they get brought to court - and sued. Then the legal department gets real busy.
For victims of child abuse the elders are instructed to be sympathetic toward the victim and direct her parents to WT publications for advice. Before this happens the victim is subjected to very detailed questions about the actual abuse (a judicial inquiry).
Watchtower legal is always called first. The elders will follow their instructions - whether or not to call the police.
The victim's life is damanged forever.
Watchtower protects their $$$ first and their own reputation second. They pay out millions of dollars every year to pay victims off and have them agree to gag orders.
