crazyguy,
It is my view that one strong reason JWs "hang in" is they fear the impact of shunning. These elders are no different, each has the same fear - plus this is the only place they can exert authority.
The Elder operates with the knowledge that the WT hierarchy is constantly monitoring them.
For an Elder to report back that they found no problem from a dissident would put that Elder into an invidious position. Never expect balanced impartiality - the Elder's self-interest is paramount.
