(stepping VERY gingerly into the fray)
First, let me make it crystal clear that I believe THAT anyone who sexually molests a child is beyond sickening. It is vile, despicable, and unforgivable. Secondly, I WAS molested by an elder and nothing was done (and no, I am not going to elaborate - it's MY past and I prefer to leave it there). So...when I make the following statement, I am NOT defending the WTS in any way. If I hadn't smashed my CD to little pieces when I left and thrown out 25 years worth of KMs - (NOW I realize they were a treasure trove for research, unfortunately) - I would scan and print this so I will have to leave it to those who are in to provide the references.
However, protocol HAS changed since I (and many others on this board) was molested. Two eyewitnesses to DIFFERENT events can indeed testify and those two events can be taken to DF a child molester. I am making NO comment or judgement about why or as to the rightness of it, I am merely verifying the procedure.
Now...if a child molester moves to a new congregation and it was never a judicial matter and no one knows about the molestation and WHEN it occurs again, to my knowledge there is no safeguard put in place so the new congregation would know about the molestation - ergo - no previous "witness". And of course, it's the BOE who would determine the veracity of the "first" witness/ie. victim. So - there are still huge, huge, huge loopholes.
If someone wants to look it up - this "new" protocol would be in a QFR in a WT.
AGAIN. I AM NOT DEFENDING THEM.
