Let us not confuse who owns the plantation with those who runs it!
Consider data as a ball of cotton on a cotton plant. Sex offenders in this analogy are the pickers of the commodity. They are legally bound to provide the data\cottonball to the DOC agent. Sex offenders are indentured servants. The agent in this analogy is really no different than the wagon master in the old south. His job is to gather the commodity efficiently as possible in bulk and deliver it to market. If he were to find one ore more of the servants delinquent in delivery or effort, a punishment results upon the slave.
