Even more unfortunately, the issue is so emotional that we can't have a reasonable discussion on it. This limits the discussion to proposals that sound good to angry people. And the opposition to those who can get angry about something else. Which limits how much reason is applied on either side.

For example, look at the idea of a national sex offenders registry, like we have in the USA. The existence of such a registry is reasonable given that we're no more successful at stopping people from being pedophiles, than we are at stopping them from being homosexuals.

But the purpose of such a list is severely undermined when an estimated quarter of the list were themselves minors when they offended. The age at which people are most likely to land on the list is 14. But a man who liked 13 year olds when he was 14, is unlikely to reoffend at 30. What is the purpose of ruining the rest of his life for a juvenile mistake?

Such discussions simply can't be had.
