DNA databanks: law enforcement's greatest surveillance tool?

Abstract

All fifty states have laws requiring the collection of DNA samples from certain classes of criminals. Genetic profiles are gleaned from these samples and entered into DNA databanks, after which they then can be accessed by law enforcement personnel and others. DNA forensic technologies can be used to identify criminal offenders, but they can also be used in ways that reveal health and other personal information about the target and even about his or her relations. Moreover, the rapid introduction of ever-changing types of DNA forensic techniques creates a potential for error. Such errors may wrongly implicate some individuals for a crime and may wrongly exculpate others. This Article examines weaknesses in state DNA databanking laws regarding the protection of genetic privacy and imposition of quality assurance mechanisms and suggests policies which state legislatures should incorporate into the state DNA databanking scheme.
