Tennessee's House Bill 473, introduced on January 28, 2025, aims to reform the handling of DNA samples collected from individuals who are arrested but not convicted. The bill mandates that if a defendant is acquitted or the case is dismissed, the Tennessee Bureau of Investigation (TBI) must destroy the DNA sample and all related records, provided there are no other pending warrants or felony convictions that would necessitate retaining the sample.

This legislative move addresses growing concerns about privacy and the potential misuse of DNA data. Advocates argue that individuals should not be subjected to indefinite data retention when they have not been convicted of a crime, emphasizing the importance of protecting civil liberties. Critics, however, express concerns about the implications for ongoing investigations and the potential for hindering law enforcement efforts.

The bill is set to take effect on July 1, 2025, and reflects a broader national conversation about criminal justice reform and the ethical management of biometric data. As discussions continue, the outcome of House Bill 473 could significantly impact how DNA evidence is treated in Tennessee, balancing the rights of individuals against the needs of law enforcement.
