The sex offender registry is a list of all convicted sex offenders in the United States. It is a compilation of all the state sex offender registries and is maintained by the Department of Justice. The registry is used by law enforcement to track and monitor the activities of known sex offenders.
The information on these registries is public, and anyone can access it. This has led to some controversy, as some people believe that the information on these registries should be private. However, the Supreme Court has ruled that the information on these registries is public, and it cannot be changed.
