This piece took a lot of courage to write, I applaud you for sharing it. In my view, we're dealing with two separate topics. Is it the responsibility of a publisher to investigate the people they publish? No, it's not. That being said, if something comes out after the fact (or worse, if they knew beforehand and published anyway), they need to take swift action and depending on the crime the person committed, a decision needs to be made about keeping that person on. This just happened in music with Marilyn Manson when he was dropped from his label after sexual abuse allegations were made public by Evan Rachel Wood. I wrote about why the label was right to drop him. https://medium.com/soundevolution-music/marilyn-manson-dropped-from-his-record-label-after-abuse-allegations-surface-bf093e036ff7?source=friends_link&sk=8098c2aa743f42c1e8ae8db3d977b473
As for the mental illness aspect, I agree mentally ill people should not be written off as criminals and jailed without getting the help they need. It's a massive problem in many countries around the world and it needs so much attention. In the case of child molestors or people involved in child pornography however, they're typically not able to reverse that particular illness. I'm sure there are those who have overcome this but everything I've ever read on the subject, they offend again. In my opinion, and this may be harsh, I don't see how they should be allowed to put their thoughts and ideas out into the world. They need help and should receive it but certain crimes and even personalities, eliminate you from doing everyone else has the right to do. It may not be their fault they are the way they are, but tell that to the child or the family of a child who has been harmed, abused, or worse, killed.
