But is, then, the response proportionate? This is the second part of the question, I'd suggest. A register alone, I have to agree with my Green colleagues, would not be appropriate. A register alone is a penalising response, but this is not a register designed to penalise; it is a post-sentence rehabilitative condition. It enables officials to walk alongside an offender and to help them reintegrate, because we do have effective clinical treatment but we don't have enough of it. We need this additional fence of the Police and Corrections being able to walk alongside our offenders until they can get into proper clinical treatment. In these circumstances, police monitoring is an effective and proportionate response.
