a few semi-ransom thoughts, or personal musings (all at least indirectly connected) …
Considering that Satan's governments and their justice systems will soon be replaced (as per Daniel 2:44), I see no problem with handling matters Jehovah's way, via spirit and truth. The buy-outs and bribes (etc.) with lawyers and police can result in far worse "justice" than practicing love as Jesus taught. On the other hand, I do feel that maintaining a photo ID register would minimise JWs changing their appearance radically, etc.
By the way, if there really is true love for Jehovah, neighbour, and oneself, each congregation would be a discerning, tight-knit group. Abusers can't stand up under the proper interchange of encouragement, and shepherding in line with Ephesians 4, Hebrews 4:13, and 2 Timothy 4. If the children in the congregation are all freely commenting in their own words, that should indicate that all is well on the home-front.
I think that anyone who wants to become a Pioneer (whether Auxiliary or Regular) should need to take a special course to qualify. The same should apply to those getting married, and to those being considered for publisher (whether unbaptised or baptised), MS, elder, (etc.) just as with becoming a Gilead missionary.
And, just as with a state driver's licence, there should be a mandatory renewal every few years, and a photo ID issued for any authorised in any JW capacity worn on a necklace just as an door-to-door salesman.
