License Plate Reader Searches Should Require a Warrant

Legal precedent increasingly suggests that law enforcement searches of historical license plate reader (ALPR) data will eventually require warrants, similar to cell phone location data, creating regulatory and compliance obligations for IT organizations supporting public safety systems. Organizations managing surveillance infrastructure should proactively implement data governance, access controls, and audit logging mechanisms to align with evolving constitutional privacy standards and prepare for inevitable legislative requirements. This shift will necessitate IT investment in warrant management systems, data retention policies, and compliance frameworks before mandatory regulations are imposed.
