I saw one of the Jonestown programmes, I'd seen things about it before and particularly remember a very good TV drama about it, Guyana Tragedy: The Story of Jim Jones, which I saw when I was young. Also read a book on the tragedy. It certainly was chilling.
Yes I did see the Bishop Ball documentary. It was awful. He had so many friends who honestly couldn't believe the allegations against him - until they were proven. I knew some people who liked and admired him as an evangelist and he spoke at one of my nephew's school events, speech day or something, which went down very well. A popular man. What a let down.
It was a sobering programme and reminded me of one I saw a few years ago, nothing to do with church, where a few men talked about how they were abused at different boarding schools in the 1980s and there was no one for them to turn to. It was stark. One of the abusers still alive (ex teacher) was interviewed too and unrepentant.
