The Tennessee Bureau of Investigation on Friday defended its use of automated license plate recognition (ALPR) systems, saying the technology has helped locate missing people and generate investigative leads while being governed by access controls and audit requirements.
Agency details benefits, oversight
ALPR cameras supplied by private vendors are already in use across Middle Tennessee, and the technology has drawn scrutiny from privacy advocates and residents concerned about data collection and potential misuse. In a statement, the bureau said ALPR information has assisted investigators in locating missing persons, identifying vehicles tied to wanted suspects and developing leads in criminal inquiries.
Officials cited two recent incidents in which ALPR data played a role: a 2026 case in which plate information from Georgia helped narrow the search for a 1-year-old taken from Tennessee; the child was located during a traffic stop, the bureau said. In a separate matter, the bureau said ALPR tracking helped locate a missing at-risk adult who had traveled from Tennessee to Colorado.
"When used properly and purposefully, Automated License Plate Recognition technology can be a valuable tool in our mission to protect and serve," TBI Director David Rausch said. "The technology must be used responsibly, with clear rules and meaningful accountability."
Access limits and prohibited uses
The bureau emphasized that ALPR results are treated as investigative leads, not conclusive evidence, and said access to the system is limited to trained, authorized personnel. It outlined policy provisions that prohibit personal, political, retaliatory, discriminatory and other unauthorized uses and said the program requires auditing and periodic reviews.
The public defense comes as local residents in Murfreesboro and elsewhere have raised questions about who can access plate data and how long it is retained. Critics have argued that pervasive plate-reading systems can create persistent location records on individuals and vehicles, with potential implications for privacy and civil liberties.
Technology in practice
Law enforcement agencies argue ALPR helps solve time-sensitive cases by providing timestamps and locations that can guide investigators. The TBI's statement framed the technology as a focused investigative tool, subject to internal controls designed to prevent misuse.
- Investigative value: Used to find missing persons and tie vehicles to suspects, according to the TBI.
- Controls claimed: Restricted access to authorized staff, audits and explicit prohibitions on unauthorized uses.
- Community concerns: Residents and privacy advocates have questioned retention, sharing and potential for discriminatory or retaliatory use.
| Use case | Result |
|---|---|
| 1-year-old taken from Tennessee (2026) | Plate data from Georgia narrowed search; child found during traffic stop |
| Missing at-risk adult | Tracked from Tennessee to Colorado |
Authorities nationwide face similar debates as jurisdictions balance crime-fighting benefits against calls for transparency, retention limits and independent oversight. The TBI's public statement underscores a posture embraced by many law enforcement agencies: emphasize operational benefits while outlining policy guardrails.
Whether that balance satisfies community concerns will likely depend on the specific retention policies, audit transparency and mechanisms for external review — details the bureau said it enforces but did not fully enumerate in its public remarks. As municipalities and state agencies consider or expand ALPR deployments, the tensions showcased in Tennessee reflect broader policy questions that state legislatures and courts may increasingly confront.
Reporting by the bureau did not provide additional specifics about retention timelines, audit frequency or third-party access. Residents and civil liberties groups continue to press for clearer public disclosure about how long plate data is stored and who may query those records.
