Prisons create criminals  The prison environment is harmful to many offenders. Consider the risk of developing a drug or alcohol addiction while incarcerated in the UK (15% of the inmates of one of the UK’s largest jails tested positive for drugs in 2006) [i] ; the risk of being subjected to sexual violence in an US prison (217,000 prisoners were subjected to sexual violence in American prisons in 2008) [ii] ; the rise in gang motivated violence and killings within prisons on both sides of the Atlantic.  Prison brings together individuals with a wide range of social and behavioural problems that incline them towards deviance and violence. These individuals are placed in closed conditions with restricted access to productive activities. In many western nations, a lack of funding and staff means that most prisoners have little to fill their time, and may be confined to their cells for up to twenty three hours a day. The privations of prison make prisoners more, rather than less likely to engage in violent or exploitative behaviour. Prisoners in overcrowded, understaffed jails are more likely to develop mental illnesses and less likely to have such conditions diagnosed and treated. The brutality of their surroundings makes prisoners more likely to seek the protection and comradeship offered by gangs or the comfort of intoxicants.  Furthermore, the shame and isolation associated with incarceration cause prisoner’s non-criminal social networks to decay. Relationships with partners or spouses may break down. Contact with children may be limited. Families may shun the offender, leaving him with a social circle comprised mainly of fellow inmates. These associations can prove toxic, leading offenders to validate each other’s behaviour and share knowledge about criminal activities.  Finally, the stigma of criminality extends to employment. Businesses may be unwilling to employ those with criminal records, limiting ex-offenders’ opportunities for social reintegration.
