Mrscedars, this is one of the most powerfully composed articles on the topic of the Watchtower's response to child abuse.
I noticed that the letter from the Watchtower does not dare tell JW parents not to inform the relevant secular authorities if their child discloses abuse by a JW - yet it reminds bodies of elders that parents have the main responsibility for their child's safety.
That being the case, JW parents should take very, very seriously the Watchtower's statement and act in accord with it. Since the letter declares that parents have the main responsibility for their child's safety, then JW parents should take action by notifying the relevant authorities - not the elders - because to notify the elders is to have their parental responsibility minimized.
