Various studies indicate that people with intellectual disability are highly represented in the criminal justice system and this appears particularly clear in the juvenile justice system. Offenders with intellectual disability tend to have backgrounds of: unstable, inappropriate accommodation placements; problematic family background; high support needs arising from factors such as drug use; history of poor educational experience and achievement, and unresolved behavioural problems. Offenders with intellectual disability tend to commit either relatively minor, but repeated offences, or a major, violent or sexual crime. The offences for which people with cognitive disability are imprisoned are overwhelmingly in the lowest severity categories. Section 2 of this Guide focuses on what support services are currently available around Australia to people with intellectual disability and criminal justice system involvement. Section 3 of this Guide aims to provide practical information for staff in DisabilityCare Australia and disability services and for advocate/agencies trying to help a person with intellectual disability and criminal justice involvement to access DisabilityCare Australia.
