You are not alone in that department.
That happened to me and a lot of the guys whose dads were elders as well. One had gotten on private reproof a lot!( And in those days there were NO such thing as "private" reproof) Another just got on public reproof. But the biggest case of one getting off light was my ex wife.
Unknown to me she was one of the biggest whores, and thief in the circuit. And her father protected her, even to the point of hiding the records of her JC meetings regarding her immoral behavior. When my dad became P.O. in her dads place he noticed that certain files were indeed missing. It was informed to him by another elder that those files were handeled "exclusivly" by her dad and the C.O personally. It involved her and two other brothers whose fathers were also P.O's from another hall.
This goes on, and on. For those that want to keep their position in the hall. Or some do it for the love of their kids.
Who knows.
