Sexually violent predator laws

Some jurisdictions may commit certain types of dangerous sex offenders to state-run detention facilities following the completion of their sentence if that person has a "mental abnormality" or personality disorder that makes the person likely to engage in sexual offenses if not confined in a secure facility. In the United States, twenty states, the federal government, and the District of Columbia have a version of these commitment laws, which are referred to as "Sexually Violent Predator" (SVP) or "Sexually Dangerous Persons" laws.
