Here in India, many publishers beg the elders not to take the case to the police due to the crazy legal system and the social ostracism which is more horrendous than the disfellowshipping arrangement.
When the legal system of the country itself is running at a snail's pace, many victims try to find support and solace in their religious community and hence I would not blame the families who go to the elders rather than the police.
Sadly, there are rising amount of cases here where people are falsely accused of child sexual abuse and the police can pretty much torture an individual to confess a crime that he did not do. You can be pretty much be beaten into a pulp even on a slight hint of accusation. Mob justice takes precedence over everything. And I can only imagine how an elder can get torn down into this mess when he gets to know about a child abuse case.
