Let me quote VA Law:
9.1-900. Purpose of the Sex Offender and Crimes Against Minors Registry.
The purpose of the Sex Offender and Crimes Against Minors Registry (Registry) shall be to assist the efforts of law-enforcement agencies and others to protect their communities and families from repeat sex offenders and to protect children from becoming victims of criminal offenders by helping to prevent such individuals from being allowed to work directly with children.
Note that the purpose of the registry, to protect against “repeat sex offenders”. Over 95% of offenders currently on the registry are not “repeat” sex offenders. Hence it is the law that is perverted and not necessarily those that are subject to it. A single offense does not a repeat offender make.
