The first is a VICE documentary from August 1, 2021 about WT's policies regarding child abuse and how their 2-witness rule effectively protects child molesters and enables them to continue to abuse children over and over, sometimes numerous children over many years. It briefly touches on the blood transfusion policy, but the child abuse issue is clearly the focus. Mark and Kimmy O'Donnell and Barbara Anderson explain their motivations and why they are now activists. The Palmer Congregation child abuse letters are mentioned as well.
The second is the May 31, 2018 episode of the A&E news documentary "Cults and Extreme Beliefs" that highlights the JW's, hosted by Elizabeth Vargas.
Both are well worth watching.
