I have found a potential way to confront abusers.
Invite your friendly pedophile to dinner. Invite the family of the kids they have abused. Set up a secret camera to record the evening. Invite two friends to play the role of child care expert and lie detector expert. Half way through the meal get the guests to reveal what they do for work and ask your guest how they feel about pedophiles? Post your findings on youtube as a friendly meal. The guilty will be apparent and cannot prosecute. The innocent will be apparent and will not prosecute.
Is this too simplistic?
