Introduction
The proposition that prisons do not work strikes at the heart of modern criminal justice, challenging the assumption that incarceration is the most effective response to criminal behaviour. Critics of the prison system point to persistently high recidivism rates, overcrowded and inhumane conditions, and the devastating social consequences of mass incarceration as evidence that prisons fail on their own terms. This essay argues that, to a significant extent, prisons do not work as currently constituted, as they neither rehabilitate offenders nor make communities meaningfully safer in the long run.
The persistently high rates of recidivism across most prison systems demonstrate that incarceration fails in its fundamental objective of reducing reoffending.
Explain
If prisons worked as intended, one would expect the experience of imprisonment to deter offenders from committing further crimes upon release. Yet recidivism data from around the world consistently shows that a large proportion of released prisoners reoffend within a few years, suggesting that incarceration does little to change criminal behaviour and may in fact reinforce it. The failure to rehabilitate is particularly pronounced in overcrowded, underfunded systems that offer minimal educational, vocational, or therapeutic programming.
Example
In the United States, a landmark Bureau of Justice Statistics study tracking over 400,000 prisoners released across 30 states in 2005 found that 76.6 per cent were rearrested within five years of release, with the highest rates of recidivism among property offenders and drug offenders. In the United Kingdom, the Ministry of Justice reported in 2022 that 25 per cent of adults released from prison reoffended within one year, rising to 39 per cent for those serving sentences of less than twelve months. Even in Singapore, which invests significantly in prison rehabilitation, the two-year recidivism rate, though declining, remained at 22.1 per cent in 2022, indicating that a substantial minority of ex-offenders continue to reoffend despite the country's relatively well-resourced prison system.
Link
These figures powerfully demonstrate that prisons do not work as rehabilitative institutions, as the majority of offenders in many systems emerge no less likely to commit crime, and in some cases more likely, than before their incarceration.
Prisons serve as breeding grounds for criminal networks and radicalisation, actively worsening the very problem they are designed to solve.
Explain
Rather than isolating offenders from criminal influences, prisons concentrate large numbers of criminals in confined spaces where gang recruitment, criminal skill-sharing, and ideological radicalisation flourish. First-time offenders and those convicted of minor offences are particularly vulnerable to being absorbed into criminal networks during their imprisonment, emerging with enhanced criminal capabilities and connections that make them more dangerous than when they entered. The prison environment thus functions as a perverse school of crime, producing more sophisticated and better-connected offenders.
Example
The radicalisation of individuals within prison systems has been extensively documented across Europe, with the French domestic intelligence service estimating in 2018 that approximately 1,500 inmates in French prisons had been radicalised by Islamist extremists, many of whom originally entered prison for petty crimes unrelated to terrorism. In the United States, gang membership in federal and state prisons is estimated at between 13 and 19 per cent of the total inmate population, with organisations such as MS-13 and the Aryan Brotherhood actively recruiting within correctional facilities. In the Philippines, the severe overcrowding of the New Bilibid Prison, which held approximately 29,000 inmates in a facility designed for 6,435, was exposed in 2014 as a hub from which drug lords continued to operate their empires with relative impunity.
Link
This confirms that prisons do not work, as the very act of incarcerating offenders in close proximity to one another frequently amplifies criminality rather than suppressing it, creating more dangerous individuals and more resilient criminal networks.
The enormous financial cost of maintaining prison systems diverts resources from more effective crime-reduction strategies such as education, mental health services, and community programmes.
Explain
Mass incarceration consumes a disproportionate share of public budgets, yet delivers diminishing returns in terms of crime reduction. The resources absorbed by building, staffing, and maintaining prisons could be far more productively invested in upstream interventions that address the root causes of crime, including poverty, educational failure, substance abuse, and mental illness. The opportunity cost of imprisonment is thus not merely financial but strategic, as every dollar spent on ineffective incarceration is a dollar not spent on proven preventive measures.
Example
The United States spent an estimated $182 billion on its criminal justice system in 2022, with approximately $81 billion allocated to corrections alone, yet maintained one of the highest incarceration rates in the world at 531 per 100,000 population without corresponding improvements in public safety. By contrast, Finland, which spends a fraction of this amount on prisons and invests heavily in social welfare, education, and mental health services, has one of the lowest incarceration rates in Europe at 51 per 100,000 and a correspondingly low crime rate. Singapore's approach of combining targeted incarceration with substantial investment in community-based rehabilitation through the Singapore Prison Service's Community Rehabilitation Centre and the Yellow Ribbon Project represents a more balanced allocation of resources, but even this model acknowledges that prisons alone are insufficient.
Link
This demonstrates that prisons do not work efficiently, as the colossal resources devoted to incarceration yield poor returns and would produce far greater improvements in public safety if redirected towards preventive and rehabilitative programmes.
Counter-Argument
Defenders of prisons argue that incarceration performs the essential function of incapacitation, physically preventing dangerous offenders from committing further crimes. They point to cases like Joseph James DeAngelo, the Golden State Killer, who evaded justice for decades while living freely in the community, as evidence that some criminals can only be neutralised through imprisonment.
Rebuttal
While incapacitation is a legitimate function, the vast majority of inmates are not violent serial offenders but non-violent drug and property offenders who could be managed more effectively through community-based alternatives. The United States, where 46 per cent of federal prisoners are incarcerated for drug offences, demonstrates that prisons are overwhelmingly used not to contain the most dangerous but to warehouse those whose behaviour could be addressed through treatment and supervision at a fraction of the cost.
Conclusion
In conclusion, prisons as they are predominantly operated around the world do not work in the sense that they fail to rehabilitate offenders, perpetuate cycles of reoffending, and impose enormous human and financial costs on societies. The evidence from nations that have adopted alternative approaches demonstrates that incarceration is neither the only nor the most effective means of achieving public safety and justice. Meaningful criminal justice reform requires a fundamental rethinking of the role of imprisonment, prioritising rehabilitation and reintegration over mere warehousing of offenders.
Introduction
While the critique of prisons is fashionable among progressive commentators, dismissing them as entirely dysfunctional ignores the essential functions they perform in protecting the public, deterring potential offenders, and delivering justice for victims of crime. No viable alternative to imprisonment has yet been demonstrated to fulfil all of these functions simultaneously and at scale. This essay contends that prisons, while imperfect and in need of reform, remain an indispensable institution whose importance becomes most apparent when one considers the consequences of their absence.
Prisons perform the essential function of incapacitation, physically preventing dangerous offenders from committing further crimes against the public during their sentence.
Explain
Whatever their limitations in terms of rehabilitation, prisons undeniably succeed in their most basic function: removing dangerous individuals from society and thereby protecting potential victims for the duration of the sentence. For violent criminals, serial offenders, and those who pose an ongoing threat to public safety, no alternative to physical incarceration has been demonstrated to provide equivalent protection. The incapacitative function of prisons is not glamorous, but it is indispensable.
Example
The imprisonment of serial offenders such as Joseph James DeAngelo, the Golden State Killer, who was sentenced to life without parole in 2020 for 13 murders and 13 rapes committed between 1975 and 1986, ensured that he could never again victimise another person. During the period between his crimes and his eventual arrest, DeAngelo lived freely in the community for over three decades, a chilling reminder of the danger posed by violent offenders who are not incapacitated. In Singapore, the indefinite detention of individuals assessed to pose serious security threats under the Internal Security Act, though controversial, reflects the government's judgment that certain individuals are too dangerous to be managed through community-based alternatives.
Link
This demonstrates that prisons do work in the crucial respect of incapacitation, as no credible alternative exists for physically preventing the most dangerous offenders from inflicting further harm on innocent members of the public.
Well-designed prison systems that incorporate meaningful rehabilitation programmes can and do reduce recidivism, proving that the problem lies in implementation rather than the institution itself.
Explain
The high recidivism rates cited by critics of imprisonment are not an inherent feature of prisons per se but rather a consequence of underfunding, overcrowding, and a lack of rehabilitative programming in many systems. Where governments have invested in evidence-based rehabilitation, education, vocational training, and post-release support within the prison framework, recidivism rates have fallen dramatically. The existence of successful prison models demonstrates that incarceration can be made to work when the political will and resources are committed to doing so.
Example
Norway's Halden Prison, often described as the most humane prison in the world, provides inmates with individual cells, access to education and vocational workshops, recording studios, and extensive counselling services, all within a secure custodial environment. Norway's recidivism rate of approximately 20 per cent within two years is among the lowest globally, demonstrating that prisons can work when rehabilitation is genuinely prioritised. Singapore's prison system similarly integrates rehabilitation into the custodial experience, with the Singapore Prison Service offering structured programmes such as the Captains of Lives framework, which provides inmates with skills training, family engagement, and throughcare support, contributing to the steady decline in the national recidivism rate over the past decade.
Link
This proves that prisons can work when properly designed and resourced, and that blanket condemnation of imprisonment as an institution is unwarranted when the real issue is the quality of implementation rather than the concept of incarceration itself.
Prisons provide a structured environment for delivering intensive therapeutic interventions to offenders with mental health issues, addiction, and behavioural disorders that community-based programmes struggle to address.
Explain
Many offenders suffer from severe mental health conditions, substance addictions, or deeply ingrained antisocial behavioural patterns that require intensive, sustained, and structured intervention. The controlled environment of a prison, when properly equipped with professional staff and therapeutic programmes, offers a unique opportunity to deliver such interventions in a setting where compliance can be monitored and distractions minimised. Community-based alternatives, while valuable for low-risk offenders, often lack the structure and resources necessary to manage individuals with complex and entrenched needs.
Example
The Drug Rehabilitation Centre system in Singapore provides a structured custodial environment in which drug abusers undergo intensive programmes combining cognitive behavioural therapy, counselling, and skills training, with aftercare support coordinated through the Central Narcotics Bureau and community supervision orders. The structured nature of the custodial setting ensures consistent participation in treatment that voluntary community-based programmes cannot guarantee, particularly for individuals with severe addictions who may lack the motivation or stability to engage with outpatient services. In the United Kingdom, the Grendon Underwood therapeutic community prison has demonstrated significant reductions in violent reoffending among inmates with personality disorders, with a 2017 study showing a 20 per cent reduction in reconviction rates compared to matched controls.
Link
This illustrates that prisons do work for certain categories of offenders, as the structured custodial environment enables the delivery of intensive therapeutic interventions that would be impractical or impossible to administer effectively in community settings.
Counter-Argument
Critics of prisons argue that persistently high recidivism rates, such as the 76.6 per cent rearrest rate within five years in the United States, prove that incarceration fundamentally fails to rehabilitate offenders and instead functions as a school of crime. They contend that the prison environment reinforces criminal identity and networks rather than breaking the cycle of offending.
Rebuttal
However, these statistics reflect the failures of specific underfunded and overcrowded systems rather than an inherent flaw in imprisonment itself. Norway's Halden Prison, which combines secure custody with extensive rehabilitation programming, achieves a recidivism rate of just 20 per cent, and Singapore's Captains of Lives framework has driven a steady decline in reoffending, proving that prisons can work when governments commit to genuine rehabilitative investment within the custodial setting.
Conclusion
Ultimately, the blanket assertion that prisons do not work is an overstatement that conflates the failures of specific prison systems with the institution of imprisonment itself. When properly administered with adequate resources, meaningful rehabilitation programmes, and a clear focus on both public safety and offender reintegration, prisons can and do fulfil their intended functions. The challenge is not to abolish prisons but to reform them, learning from the successes of systems that have demonstrated that incarceration and rehabilitation are not mutually exclusive.
