This "learning" does not seem to me to be a sane evolution but rather a degeneration. A friend of mine describes how his father being a policeman let him see the worst in people. And there's a logical progression from seeing the worst to thinking the worst to not caring if you ruin someone's life through abusive prosecution. As I mentioned, catching a determined pedophile is hard but the "just put people in jail for nuisance and hope some of them are pedophiles" isn't protecting or helping anyone ... except an abusive and metastasized (in)justice system.
