Rodriguez wasn't on parole. He had served his maximum time on his previous sentence(s), so the state couldn't legally supervise him.
But why a level 3 sex offender like him didn't have an automatic review for civil commitment is beyond me--especially because his sex offender classification meant he would be VERY likely to reoffend--is beyond me.
Civil convictions aside, I can't understand how someone can have a third conviction for a violent crime and the state can't put them away for good.
