Not of itself more difficult.... It will be larger because there will be more people.
We don't have any good evidence in New Zealand or internationally as to whether in those countries with rising rates of incarceration the people coming into prison have more mental health or addiction problems than the prison populations had before that rise occurred. We don't have good epidemiology internationally to tell us whether that is so. But if the prison population thrives we will have more people with drug and alcohol problems in prisons, so we will need better health responses for them.
National and international controversy is being debated most clearly at the moment south of the border, because of the fiscal level that they've reached, as to what the right model for the war on drugs is: when is it right to use a more therapeutic response--the drug courts and those kinds of models; when is it necessary to use incarceration as the appropriate response; and who are the people we should be incarcerating for public protection, to hold people to account for the severity of their actions and the ongoing risk they may present to the public? Each society sets those thresholds a bit differently.
New Zealand has a higher crime rate than Canada, so that explains some of the increase. But some of the moves to mandatory sentencing of certain sorts--and we've even now got a three-strikes piece of legislation, which I'm not terribly enthusiastic about--do create other problems.
For me, the best model comes from an international group of criminologists and criminal psychologists. The “good lives” model was developed by Tony Ward and the Victoria University of Wellington, New Zealand, with a number of international colleagues, including Canadian, North American, Australian, and British colleagues. That model sees offenders not as a different class of being, but as fellow travellers, people who have problems in life that overlap but are not entirely separate from ourselves, and for whom we engender crucially important aspects of common humanity, hope, and accountability. So if we imprison people for the things they have done wrong, and rightly so, then that space we bring them into needs to be as healthy as we can make it as we hold them to account, and it gives them the opportunity to learn better ways, rather than have their maladaptive old ways simply reinforced.
We're probably good at reinforcing maladaptive old ways, and at times with the young offenders teaching them bad ways, rather than creating incarceration as a different sort of opportunity, and that's holding people to account. One's duty as a citizen means respecting the rights of other citizens. Imprisonment is a vital means of passing that message to people: that if you have violated the rights of others you need to be held to account for that and pay a debt; and while you are doing that, we will also give you the opportunity--it's not necessarily the right, but the opportunity--to rebuild your life in a better way.
Getting that mix of messages right, as well as having long-term incarceration for that small number of people who do present a very long and serious risk to the population as a whole, is that kind of balance we need to get. I'm not sure New Zealand has got any of that right, but I think we need all of those pieces on the agenda as we discuss these issues.
