229A.1  Legislative findings.
  The general assembly finds that a small but extremely dangerous group of sexually violent predators exists which is made up of persons who do not have a mental disease or defect that renders them appropriate for involuntary treatment pursuant to the treatment provisions for mentally ill persons under chapter 229, since that chapter is intended to provide short-term treatment to persons with serious mental disorders and then return them to the community. In contrast to persons appropriate for civil commitment under chapter 229, sexually violent predators generally have antisocial personality features that are unamenable to existing mental illness treatment modalities and that render them likely to engage in sexually violent behavior. The general assembly finds that sexually violent predators’ likelihood of engaging in repeat acts of predatory sexual violence is high and that the existing involuntary commitment procedure under chapter 229 is inadequate to address the risk these sexually violent predators pose to society.
  The general assembly further finds that the prognosis for rehabilitating sexually violent predators in a prison setting is poor, because the treatment needs of this population are very long-term, and the treatment modalities for this population are very different from the traditional treatment modalities available in a prison setting or for persons appropriate for commitment under chapter 229. Therefore, the general assembly finds that a civil commitment procedure for the long-term care and treatment of the sexually violent predator is necessary. The procedures regarding sexually violent predators should reflect legitimate public safety concerns, while providing treatment services designed to benefit sexually violent predators who are civilly committed. The procedures should also reflect the need to protect the public, to respect the needs of the victims of sexually violent offenses, and to encourage full, meaningful participation of sexually violent predators in treatment programs.
