Automated License Plate Readers in Iowa: Review and Recommendations - ACLU of Iowa
By Mia Savicevic and Ethan Miner
This report is a focused look at the growing use of automated license plate readers (ALPRs) by law enforcement agencies across Iowa—a surveillance tool that poses serious risks to Iowans’ privacy and civil liberties. ALPRs are not speed cameras. They are not “red light” cameras. Instead, they are cameras used along roadways throughout Iowa that quickly take thousands of snapshots of license plates as vehicles drive by. That information can then be fed into a network of nationally shared databases that has too few privacy protections and is subject to abuse. More details about ALPRs generally can be found on the ACLU of Iowa website. Unlike other traffic cameras, ALPRs aren’t activated because you violated a law. They record you and every other person who drives by, simply to build a database of vehicle information. ALPRs can take hundreds of photos in a matter of minutes. And unlike ordinary surveillance cameras, where data is either not shared or shared in a more limited manner, the main purpose of ALPRs is to feed this information into a database. To investigate how this technology is being used, the ACLU of Iowa engaged the Technology Law Clinic at the University of Iowa College of Law to conduct independent research on the use of ALPRs in Iowa. We sent open records requests to a broad cross-section of 48 law enforcement agencies across the state, to larger towns, to smaller communities, and to Iowa’s college towns. The study was not comprehensive of all ALPRs in Iowa. Of the 48 agencies that were selected, 5 did not respond to our records request before publication: the Des Moines Police Department, the Clinton Police Department, the Fayette Police Department, the Fremont Police Department, and the Mills Police Department.While researching this project, the clinic also identified agencies (see Appendix D) that have accessed other Iowa cities’ or counties’ ALPR databases, whether they have their own ALPRs or not.
