Another thing that is extremly harmful is the judicial committee is not really set up to establish whether wrongdoing has occurred. If elders did not suspect or believe someone had sinned then there would be no committee. The committee starts from the premise that someone has indeed breached the rules either of scripture or the society.
The purpose of the committee is to see whether someone is sorry, after all you are not excommunicated for the sin you are disfellowshipped for not expressing the appropriate level of repentance. This means that those entering the committee are focusing on stressing how sorry they are not on investigating whether they were culpable or not. This can mean that a victim of a sexual assault or molestation is questioned regarding whether they did anything to encourage the behaviour, and how much they were to blame for what happened to them. This can be incredibly damaging the victim is made to feel a measure of responsibility, leading to guilt and PTSD. The process of trying to show evidence of repentance reinforces the idea that they have a measure of blame.
Elders are made to think that they are being guided by god's spirit and thus this can lead to complacentcy that whatever they do is god's will. They don't have to be experts in counselling, safeguarding children or know how to deal with rape victims because God will make it turn out all right. This means that their clumsy questioning and personal bagage can lead to dreadful errors being made that can increase the trauma of the experience. Also the fact that any form of therapy is regarded with suspision means that the victims are left high and dry with nowhere to go to get the support and therapy they need.
