I wonder if the mothers are speaking the accepted responses because they are threatened with the loss of their children.
Which, in most cases, a mother could be coerced into saying whatever her captors wanted.
The cult leaders could be threatening the women by telling them if the authorities didn’t like their lifestyle the children could be removed from the mothers forever.
This situation needs to be monitored very closely. There is an obvious pre-judgment that is occurring here. I'm of the opinion that court ordered advocates for the children should be the NORM in this situation with all contact between social services and the children being recorded and conducted in the presence of the child advocates.
