California police and sheriffs are failing to protect the privacy of drivers on city streets, the California State Auditor’s office determined after a seven-month investigation into the use of automated license plate readers (ALPRs) by the Los Angeles Police Department and three other local law enforcement agencies. California State Senator Scott Wiener sponsored the State Auditor’s report.
The auditor raised a long list of concerns, including fundamental problems with police ALPR policies, failure to conduct audits, and the risk of ALPR data being abused to surveil political rallies or target immigrant populations. In addition to Los Angeles, the auditor investigated the Fresno Police Department, Sacramento County Sheriff’s Office, and Marin County Sheriff’s Office. The auditor indicated that the problems are likely prevalent across 230 California law enforcement agencies using ALPRs.
