I think it is telling that they make it sound like the abuse is happening from people the kids don't know or for those on the outside. This says nothing about being careful about people you do know. The research shows that the majority of sexual abuse happens with someone the child knows and trusts not from some creepy green blob.
It is fine to reference articles, but how about explaining how that is handled in the congregation and making THOSE policies and procedures clear? They can't because it would increase rather than decrease their culpability in the eyes of anyone actually paying attention.
