Fed-up - "Many abusers abuse more than one child."
That's another problem the WT heirarchy has serious trouble with, for a number of reasons.
First, because the evidence supporting that conclusion somes from "Satan's World", and therefore automatically viewed with skepticism and suspicion.
Secondly, because it conflicts with the ideology-based belief that an individual who "sins" can successfully turn his or her life around and avoid repeating the offense by means of faith and prayer (rather than secular "Worldy" means of rehabilitation, such as counseling, 12-step programs, etc.).
Authoritarian regimes are absolutely loathe to admit (to themselves or outsiders) that they even have internal problems, let alone acknowledge that outsiders might be far more qualified and skilled at handling said internal problems that they themselves could ever be.
Not to mention that ideology-based reasoning completely fails to take into consideration the fact that sexual predation, in addition to being one of the absolute worst offenses human beings can commit, has many aspects in common with addiction, which medical science and psychology (again, more aspects of "Satan's World") have demonstrated pretty conclusively is virtually impossible to eliminate... the vast majority of addicts inevitably relapse, and for predatory sex addicts, fairly extreme measures are necessary to curtail those relapses.
Sooner or later, those measures cannot help but come into conflict with WTS policies regarding worship, proselytizing, fellowship, etc., and in the WTS, policies and doctrines are viewed as - for all intents and purposes - the same (whether the average JW is aware of this or not).
To the R&F, doctrine cannot be wrong, therefore policy cannot be wrong.
