Crime

The non-identity problem of professional philosophers

By Charles Foster

Philosophers have a non-identity problem. It is that they are not identified as relevant by the courts. This, in an age where funding and preferment are often linked to engagement with the non-academic world, is a worry.

This irrelevance was brutally demonstrated in an English Court of Appeal case,  (‘the CICA case’) the facts of which were a tragic illustration of the non-identity problem. Continue reading

Using AI to Predict Criminal Offending: What Makes it ‘Accurate’, and What Makes it ‘Ethical’.

Jonathan Pugh

Tom Douglas

 

The Durham Police force plans to use an artificial intelligence system to inform decisions about whether or not to keep a suspect in custody.

Developed using data collected by the force, The Harm Assessment Risk Tool (HART) has already undergone a 2 year trial period to monitor the accuracy of the tool. Over the trial period, predictions of low risk were accurate 98% of the time, whilst predictions of high risk were accurate 88% of the time, according to media reports. Whilst HART has not so far been used to inform custody sergeants’ decisions during this trial period, the police force now plans to take the system live.

Given the high stakes involved in the criminal justice system, and the way in which artificial intelligence is beginning to surpass human decision-making capabilities in a wide array of contexts, it is unsurprising that criminal justice authorities have sought to harness AI. However, the use of algorithmic decision-making in this context also raises ethical issues. In particular, some have been concerned about the potentially discriminatory nature of the algorithms employed by criminal justice authorities.

These issues are not new. In the past, offender risk assessment often relied heavily on psychiatrists’ judgements. However, partly due to concerns about inconsistency and poor accuracy, criminal justice authorities now already use algorithmic risk assessment tools. Based on studies of past offenders, these tools use forensic history, mental health diagnoses, demographic variables and other factors to produce a statistical assessment of re-offending risk.

Beyond concerns about discrimination, algorithmic risk assessment tools raise a wide range of ethical questions, as we have discussed with colleagues in the linked paper. Here we address one that it is particularly apposite with respect to HART: how should we balance the conflicting moral values at stake in deciding the kind of accuracy we want such tools to prioritise?

Video Series: Tom Douglas on Using Neurointerventions in Crime Prevention

Should neurointerventions be used to prevent crime? For example, should we use chemical castration as part of efforts to prevent re-offending in sex offenders? What about methadone treatment for heroin-dependent offenders? Would offering such interventions to incarcerated individuals involve coercion? Would it violate their right to freedom from mental interference? Is there such a right? Should psychiatrists involved in treating offenders always do what is in their patients’ best interests or should they sometimes act in the best interests of society? Tom Douglas (Oxford) briefly introduces these issues, which he investigates in depth as part of his Wellcome Trust project ‘Neurointerventions in Crime Prevention’ (http://www.neurocorrectives.com).

The Ethics of Compulsory Chemical Castration: Is Non-Consensual Treatment Ever Permissible?

By Jonathan Pugh

Tory Grant, the justice minister for New South Wales (NSW) in Australia, has announced the establishment of a task force to investigate the potential for the increased use of anti-libidinal treatments (otherwise known as chemical castration) in the criminal justice system. Such treatments aim to reduce recidivism amongst sexual offenders by dramatically reducing the offender’s level of testosterone, essentially rendering them impotent. The treatment is reversible; its effects will stop when the treatment is ceased. Nonetheless, as I shall explain below, it has also been linked with a number of adverse side effects.

Currently, in New South Wales offenders can volunteer for this treatment, whilst courts in Victoria and Western Australia have the discretion to impose chemical castration as a condition of early release. However, Grant’s task force has been established to consider giving judges the power to impose compulsory chemical castration as a sentencing option. Notably though, New South Wales would not be the first jurisdiction to implement compulsory chemical castration in the criminal justice system. For instance, Florida and Poland also permit compulsory chemical castration of sex offenders.

Strange brew: opiates from yeast

A recent series of papers have constructed a biochemical pathway that allows yeast to produce opiates. It is not quite a sugar-to-heroin home brew yet, but putting together the pieces looks fairly doable in the very near term. I think I called the news almost exactly five years ago on this blog.

People, including the involved researchers, are concerned and think regulation is needed. It is an interesting case of dual-use biotechnology. While making opiates may be somewhat less frightening than making pathogens, it is still a problematic use of biotechnology: millions of people are addicted, and making it easier for them to get access would worsen the problem. Or would it?

Stopping the innocent from pleading guilty

Written by Dr John Danaher.

Dr Danaher is a Lecturer in Law at NUI Galway. His research interests include neuroscience and law, human enhancement, and the ethics of artificial intelligence.

A version of this post was previously published here.

Somebody recently sent me a link to an article by Jed Radoff entitled “Why Innocent People Plead Guilty”. Radoff’s article is an indictment of the plea-bargaining system currently in operation in the US. Unsurprisingly given its title, it argues that the current system of plea bargaining encourages innocent people to plead guilty, and that something must be done to prevent this from happening.

I recently published a paper addressing the same problem. The gist of its argument is that I think that it may be possible to use a certain type of brain-based lie detection — the P300 Concealed Information Test (P300 CIT) — to rectify some of the problems inherent in systems of plea bargaining. The word “possible” is important here. I don’t believe that the technology is currently ready to be used in this way – I think further field testing needs to take place – but I don’t think the technology is as far away as some people might believe either.

What I find interesting is that, despite this, there is considerable resistance to the use of the P300 CIT in academic and legal circles. Some of that resistance stems from unwarranted fealty to the status quo, and some stems from legitimate concerns about potential abuses of the technology (miscarriages of justice etc.). I try to overcome some of this resistance by suggesting that the P300 CIT might be better than other proposed methods for resolving existing abuses of power within the system. Hence my focus on plea-bargaining and the innocence problem.

Anyway, in what follows I’ll try to give a basic outline of my argument. As ever, for the detail, you’ll have to read the original paper. Continue reading

McMahan’s Hazardous (and Irrelevant) Thought Experiment

Written by Professor Allen Buchanan and Professor Lance K. Stell  

 

This is a response to an earlier post, by Jeff McMahan, about the right to carry guns, http://blog.practicalethics.ox.ac.uk/2015/04/a-challenge-to-gun-rights.

Before we criticize McMahan’s argument, it is important to ascertain its implications: Assuming that, as McMahan thinks, there is no moral right to gun ownership, what follows, practically speaking? One might think that, given the number of gun deaths, it follows that there should be a legal ban on gun ownership. As we shall show, however, that conclusion does not follow.  Whether or not gun ownership should be banned is independent of whether there is a moral right to gun ownership. We will show that McMahan has not established that there is no moral right to gun ownership, but that even if he had, he would not have thereby shown that there should be a ban on gun ownership.

Should we punish crimes from the distant past?

Former Auschwitz SS officer Oskar Gröning is currently being tried as an accessory to murder for his role as an administrator in the extermination camp, and the trial has stirred up a lot of debate. One strand of the debate addresses the question whether Gröning was complicit in the extermination of prisoners, and whether he was culpable for this complicity. (Roger Crisp wrote a fascinating post on this a couple of weeks back.) But another strand – and the strand that I want to look at here – has addressed the question whether former Nazi war criminals should be tried and punished for deeds in their distant past. Eva Mozes Kor, an Auschwitz survivor and witness in Gröning’s trial has claimed that he shouldn’t be tried, though he should use his knowledge to help fight holocaust denial.

Let’s suppose that Gröning was indeed a culpable accomplice to murder. Should he then be punished? More generally, should serious crimes from decades go be punished? My intuition is that they should, but reflecting on why I have found it is not straightforward to defend this view. Continue reading

A Challenge to Gun Rights

Written By Professor Jeff McMahan

 

On this day in the US, around thirty people will be killed with a gun, not including suicides.  Many more will be wounded.  I can safely predict this number because that is the average number of homicides committed with a gun in the US each day.  Such killings have become so routine that they are barely noticed even in the local news.  Only when a significant number of people are murdered, particularly when they include children or are killed randomly, is the event considered newsworthy.

 

Yet efforts to regulate the possession of guns in the US are consistently defeated. Continue reading

Treatment for Crime Workshop (13th – 14th April) – Overview

Practical ethicists have become increasingly interested in the potential applications of neurointerventions—interventions that exert a direct biological effect on the brain. One application of these interventions that has particularly stimulated moral discussion is the potential use of these interventions to prevent recidivism amongst criminal offenders. To a limited extent, we are already on the path to using what can be described as neuro-interventions in this way. For instance, in certain jurisdictions drug-addicted offenders are required to take medications that are intended to attenuate their addictive desires. Furthermore, sex-offenders in certain jurisdictions may receive testosterone-lowering drugs (sometimes referred to as ‘chemical castration’) as a part of their criminal sentence, or as required by their conditions of parole.

On 13-14th April, a workshop (funded by the Wellcome Trust) focussing on the moral questions raised by the potential use of neuro-interventions to prevent criminal recidivism took place at Kellogg College in Oxford. I lack the space here to adequately explore the nuances of all of the talks in this workshop. Rather, in this post, I shall briefly explain some of the main themes and issues that were raised in the fruitful discussions that took place over the course of the workshop, and attempt to give readers at least a flavour of each of the talks given; I apologise in advance for the fact that I must necessarily gloss over a number of interesting details and arguments.
