" Do you really think that such a person will molest a child in front a second witness?"Do you think that such a person will molest an adult in front of a second witness?
Don't forget, you had asked the question "Why was there only one witness to abuse? The answer is obvious.
The point of your response here isn't very clear, but you do raise an important issue regarding a Watchtower double standard. According to Duet 2:27 two witnesses are not required in the case of sexual crimes.
27 for he found her in the field, the betrothed damsel cried, and there was none to save her. (American Standard Version)
If there was no one to save an adult victim of rape, who cried out for help, then there was obviously no one there to be a second witness. Despite that the rapist was to be put to death (v 25, 26). It is clear that other kinds of evidence were brought in for consideration, but Watchtower only accepts the testimony of two witnesses to catch a child molester.
To detect those other kinds of evidence you need professionals such as the police, but in almost all cases Watchtower refuses to contact any authority.
Watchtower's double standard is that the Organization claims it's hands are tied by the Bible and the two witness rule, while completely ignoring another part of the Bible.
I realize that this whole child abuse issues exists because it is easy to use against the Watchtower.
Ah, the persecution card again. Forget about the terribly abused child victims but weep for poor Wathtower for hiding the entire sordid issue, as if the whole world is out to get them.
