Ok I get your point, and you seem to be arguing the same as the article - the value of a register of sex offenders is not as great as it might seem.
it depends I suppose on whether the register has much of an effect. I mean if you reoffend even after going to jail, having your name on a list seems unlikely to help.
I think there needs to be a list of convicted felons somewhere that is widely accessible with their addresses so people are aware they are in the neighborhood. However, I don't think it should list them as "sex offenders" or the like. There is an unearned stigma in many of the cases. [e.g. urinating in public gets you on THE LIST]
