This study examined arrestee DNA laws (laws that allowed testing of arrestees DNA pre-adjudication), their implementation in the field and their subsequent effects on agency operations as well as their success in aiding investigations in the 28 states that have these laws. The study investigated five specific questions: What states have passed legislation authorizing the collection of DNA from arrestees? How do the laws and policies regarding collecting DNA from arrestees differ by state? How have the courts ruled on these new laws? How have arrestee DNA laws been implemented in each state? What has been the impact of requiring DNA collection from arrestees on state crime laboratories and other involved agencies? What evidence is available to determine the effects of collecting DNA from arrestees on public safety or other criminal justice outcomes? To answer these questions, researchers used a mixed methods data collection plan, including reviewing relevant statutes and case law, interviewing state and federal Combined DNA Index System (CODIS) laboratory staff and other forensic experts, and collecting descriptive data from state laboratories.
