N.J. Stat. § 53:1-20.18
The Legislature finds and declares that DNA databanks are an important tool in criminal investigations and in deterring and detecting recidivist acts. It is the policy of this State to assist federal, state and local criminal justice and law enforcement agencies in the identification and detection of individuals who are the subjects of criminal investigations. It is therefore in the best interest of the State of New Jersey to establish a DNA database and a DNA databank containing blood or other biological samples submitted by every person convicted or found not guilty by reason of insanity of a crime or a specified disorderly persons offense and arrested for certain violent crimes. It is also in the best interest of the State of New Jersey to include in this DNA database and DNA databank blood or other biological samples submitted by juveniles adjudicated delinquent or adjudicated not delinquent by reason of insanity for acts, which if committed by an adult, would constitute a crime or a specified disorderly persons offense and by every juvenile arrested for certain violent crimes.
The Legislature further finds and declares that the minimal intrusion on an individual's privacy interest resulting from a DNA test is justified by the compelling governmental interests advanced by DNA analysis, for those who are convicted, adjudicated or found not guilty by reason of insanity for crimes or specified disorderly persons offenses, as well as for those who are arrested for certain violent crimes. It further finds that DNA testing enhances the State's ability to positively identify an offender, to ascertain whether an individual may be implicated in another offense, and to establish positive identification in the event the offender becomes a fugitive.
The Legislature finds, as did the Supreme Court of New Jersey, that there is a compelling parallel between the taking of DNA and fingerprinting, and that the purposes of DNA testing demonstrate "special needs" beyond ordinary law enforcement.
