I’ve watched BBC Panarama’s Suffer the Little Children a few times which to be fair is quite old now but powerful. Are there any more documentaries on YouTube etc. that are similar?
I had a link to a website from Canada that features documentaries on pretty much every subject. I'm sure you will find some that you may like. However, I can't find the link. I'll send it to you as soon as I find it (I really need to organize my bookmarks).
