The President of the U.S. has signed into law The John Walsh Child Protection & Safety Act which will among other things provide 500 new federal marshals to fight pedophiles and create a new easily accessible sex offenders finder database.
The Watchtower Society has not cared to divulge the names of offenders among their ranks from the Governing Body down to the local kingdom halls but now human society in the U.S. is doing an end-run around them.
I recommend that since you know the names of JWs in your area and likely too some who are serving at the various Bethel buildings and farm sites, that as soon as the new federal database goes online on the internet, you type in zipcodes to check to see if any of the names there are familiar to you.
Also, if you are in another nation which does not have such a database, then I urge you do all you can to lobby for one. Save The Kids And We Who Are Their Parents.
