The Third Circuit Court of Appeals ruled this week that police officers may collect DNA samples from persons under arrest, finding that a DNA sample is no more than a fingerprint "for the twenty-first century." The court emphasized the government's compelling interest in identifying suspects and the unique attributes of DNA evidence to support its decision.
Civil rights groups, including the ACLU, argue that collecting a DNA sample is more invasive than fingerprinting an arrestee, and a violation of privacy, while proponents of DNA sampling maintain that the practice is constitutional because arrestees have a low expectation of privacy.
