As part of their preventative measures, JCW has a fascinating technique that I think has bearing on this discussion: They have a “Wall of Shame”, filled with names and pictures of suspected (although not necessarily proven) child abusers.
I disagree with this. Until properly proven, you cannot do anything publicly. Putting up a photograph of a suspected molester on a wall dedicated to suspected criminals is a disgraceful thing to do. Whatever you can do once convicted is debateable, but to hang somebody without proof?
