No One Knows: offenders with learning disabilities and learning difficulties

There is a lack of clarity about the prevalence of offenders with learning disabilities and learning difficulties. However, it is clear is that, regardless of actual numbers, many offenders have learning disabilities and learning difficulties that interfere with their ability to cope within the criminal justice system. No One Knows is a UK‐wide programme led by the Prison Reform Trust that aims to effect change by exploring and publicising the experiences of people with learning disabilities and learning difficulties who come into contact with the criminal justice system. The article highlights the aims of the No One Knows programme and considers recent research on prevalence, drawing attention to some of the reasons for the different findings.
