"determine things like the context, nature, and degree of any acts under investigation. The point being that if you can't effectively isolate(bull ) and identify the actual problem and it's associated behaviors(bull) you can't address the issue and help the person properly "
That is a load of garbage! Perhaps WTBTS should had paid elders way to a one time forensics class. How about investigation and questioning? Investigation only want fact to the case. It is not about helping a sinner.
Elders are NEVER about helping people.
How could you bibically help many who confess sins? Confession of sin should never be a CASE for disfellowshipping but a cry for help!
How could any elder place WTBTS over the Bibles truth?
It is obvious from the majority of elders reply that helping others is not part of elders school.
Your father has been part of this good old boy club for years it is his way of socializing.
I would suggest to take him to a seniors gathering.
Hopefully, he will enjoy fellowship. Most cities have them.
Be apart of his activities. Take him to senior dances and lunches.
