The document discusses risk management of sexual offenders in communities. It covers topics like civil commitment laws, sex offender registries, community notification, and actuarial risk assessment tools. Specifically, it notes that civil commitment targets high risk individuals with treatable mental disorders to protect the public through least restrictive means. It also discusses how sex offender registries in Canada aim to provide police information to investigate sexual crimes by identifying possible suspects near offense sites. However, community notification laws may heighten fear and impede offender reintegration without public education. Actuarial tools also have limitations and error rates in accurately assessing risk.
