It should take into account rehabilitation. If crime occurs because of a defect—say psychological, moral, or social—it can be corrected or prevented in future crime. And this is a particularly important part of the system, which three strikes seems to actively act against, because once you are on those three-strike offences, you lose the ability to participate in those programmes which give you a better grounding outside of prison and which enable you to take on a fulfilling and hopeful life, which inevitably leads to less offending from that person in the future. And the underlying logic of three-strikes legislation is that a failure in deterrence can be compensated by increases in incapacitation. There's no evidence that that is the case in the way that it's playing out here in New Zealand or in the United States, where this legislation was borrowed from.
