I've heard this excuse too:
"It is not our job as a religion to imprison criminals."
No one is asking them to take on the role of a cop, judge or prison guard. They are only being asked to turn the matter over to those qualified to handle the situation.
WT policies aside, how can human beings, with an INBORN inclination to stop at nothing to protect a child - even one who is not their own - be so oblivious to what is a common sense approach to a molestation accusation? Any dirt bag on the street, if approached by a child seeking help over something like this, would IMMEDIATELY turn directly to the police... leading the child by the hand.
How is it that the most righteous, loving people on the planet cannot grasp the simplicity of the correct response?
