Nine police cars in Henderson are now equipped with extra eyes - license plate scanners. Each vehicle has four cameras, and they have the ability to scan one plate each second or nearly 30,000 plates in an 8 hour shift. The device compares the plates it scans to a database of “wanted” license plates. The police say that the scanner records a plate only if it’s a match in the system, but the ACLU of Nevada is concerned about the privacy implications of this new scanning system.
