The previous speaker from the Green Party, Golriz Ghahraman, is correct that there are differing opinions on the efficacy of sex offender registers, particularly the sort of behaviour that we see in the US, where they are aimed at naming and shaming. I do not see in my own research proof of the efficacy of a naming and shaming approach. But what people who treat sex offenders consistently say is that because this is compulsive behaviour, because it has very deep roots in the way the person sees their sexuality and the way they relate to others, it is necessary to continue to monitor that person and to keep them wrapped in layers of monitoring.
