Her qualifications are sorely lacking, according to the Royal Commission.
My impression is Applewhite might be pretty good at offering advice on how to improve an organization's policy in response to child abuse, but when it comes to standing up in public for a policy that has weaknesses she's not very objective about admitting those weaknesses along with her recommendations for improving them. In Watchtower's case the RC had to lead her to weaknesses in Watchtower policy and then practically drag admissions out of her that the weaknesses exist. Telling to me was how she was willing to accept what Watchtower published in its own literature as representative of how JWs in general feel. This is not objective in the least!
This gal was hired by Watchtower to do one thing: make its policy look nicy-nice to the RC. Problem is, that's not what the RC is concerned with. The RC wants to know what are the weaknesses in Watchtower policy and what is going to be done about those weaknesses. Applewhite spent her time on the stand attempting an apologia when she should have concentrated on sharing objective expertise regardless of who paid her.
