Mary is a hypothetical person facing a situation that some Christians have faced. The way she handles the situation represents how some have applied Bible principles in similar circumstances.
In their Commentary on the Old Testament, Keil and Delitzsch state that a person would be guilty of error or sin if he “knew of another’s crime, whether he had seen it, or had come to the certain knowledge of it in any other way, and was therefore qualified to appear in court as a witness for the conviction of the criminal, neglected to do so, and did not state what he had seen or learned, when he heard the solemn adjuration of the judge at the public investigation of the crime, by which all persons present, who knew anything of the matter, were urged to come forward as witnesses.”
So, if you know of a pedophile, and "knew of their crime", "could appear in court as a witness," "neglected to do so" What would happen to you?
Would you be DF'd? Lose your life at Armageddon? In many of the pedophile cases among JW's that I have read, it's the people who "stand up for what is right," who "go before the judge to testify" that get DF'd. The honest ones get punished, & get called apostates...
Why? for "speaking against the glorious ones,' for testifying in court "in opposition to the WT."
