Much good advice, for me, I would write to that BOE and inform them that you will take action for defamation against them, collectively and individually, if a mere whisper of the statement "we had no idea of how manipulative he can be" surfaces again. Second, you are advising the authorities of their individual names for the purpose of recording them as individuals who should never be in the company of minors, either as a group or as individuals. Their allowing two of their number to interview about sensitive matters, a two year old child is child abuse and should be dealt with as such. Further, that when in your legal custody, your daughter is a member of your household and can enjoy all your proper activities, if they intimate, tell her, or tell others, ,such as her mother, what she does at your house is wrong when plainly it is proper, they are further laying themselves open to action for defamation and action for child abuse by words .
They show by their actions that they are unfit to be elders and I would copy correspondence to the Society and Circuit Overseer.
