Police departments across Washington are dealing with new limits on license plate readers, which have led to concerns about privacy and government surveillance. The new law, signed by Gov. Bob Ferguson, limits how police can use the technology, restricts storage, sharing, and sharing of data near certain locations. Advocates argued that the technology allows for widespread data sharing, including with federal agencies. Some police departments have halted use of license plates while reviewing policies to comply with the new law. The ACLU of Washington has criticized the law, while others have already shut down systems. The company behind many of the cameras is helping agencies comply by shortening data retention and limiting how data can be shared.
