A sex offender registry is a public database that lists individuals who have been convicted of sexual offenses. The purpose of the registry is to provide information to the community about these individuals, helping to enhance public safety and awareness. Registries typically include details such as the offender's name, address, and the nature of their offense. Each state in the United States maintains its own registry, and the information is often accessible online. The laws governing the registry can vary by state, including how long individuals must remain on the list and the level of detail provided to the public.
