A police usage policy for automatic license plate readers (ALPRs), recently obtained by 404 Media, provides an explicit example of how police departments avoid revealing when they use the AI-powered surveillance tools. In some communities, a significant portion of ALPR reports have been false positives, leading to many unnecessary traffic stops and arrests. One usage policy advises police officers in Wapello County, Iowa – in all-caps text – never to mention ALPR usage when making traffic stops or writing reports. Furthermore, even when required to mention the technology in reports, officers are advised to describe it vaguely as "county resources." Officers are often advised to describe ALPR usage in vague terms in reports because they are subject to public information requests.
