OldHippie, I have a better idea about perverts. The body of elders could do the right thing and call the Police. They should make it clear that they are not going to tolerate any abuses against children, from anyone, anywhere. This should happen if the man in question were a member of the Governing Body itself. Also, the Governing Body could also be hit by "new light" and decide that Jehovah just told them to stop being accesories to the fact. Your post sounds like "well, if you want to know who are perverts, then we need to have this check on people". You know full well that this is a false alternative. Perverts DON'T get reported to the Police or anything. And, if what I read here is true, it's even perfectly possible that everybody knows someone else is a pervert but, if he has good standing, he is a good member of the congregation.
The Catholic Church has sent priests to different parishes to evade justice. Do you have the feeling that sending a pervert to another congregation, with an impeccable publisher card and a very nice worded letter, could be used in the same fashion? I am sure it could.
I have another idea. Since the Kingdom is not to take place in this world, why don't we stop giving any earthly authority to guys who are not better than the rest? Why don't we recognize that they are "imperfect men", so it's not wise to let them use their imperfect reasoning to do perfect harm to others?
The mere idea that your fate depends on what someone else says about you gives me the goosebumps. I can see a zillion opportunities for abuse.
In my humble opinion, the right thing to do should be simply do away with such a letter. And simply not tolerate any abuse against anyone.
