Do you trust local police to use automated license plate reader technology in your community?

The Milwaukee Police Department has stopped sharing license plate reader data with outside law enforcement agencies. These changes were introduced alongside a new seven-day image retention policy to address growing public privacy concerns.

Why it matters

The policy shift aims to balance public safety needs with resident privacy by limiting the scope of surveillance investigations. By restricting data access to internal supervisors, the department intends to curb the reach of its camera network.

The Milwaukee Police Department now utilizes three vendors for its license plate reader technology. Access to the gathered data is currently restricted solely to department supervisors.

The players

Milwaukee Police Department

This is the primary law enforcement agency for the city of Milwaukee responsible for the oversight of public safety and surveillance operations.

Flock

Flock is a technology vendor that provides automated license plate reader systems and software solutions to law enforcement agencies.

The details

While the department has cut direct sharing with external agencies, federal entities may still access some information through indirect third-party sources. Technology providers and private businesses continue to operate their own independent data-sharing networks.

Legal Context

The department's move aligns with a broader trend of municipalities revising surveillance policies to comply with evolving privacy expectations. Local courts and legislatures are increasingly scrutinizing how license plate data is shared between different government entities.

Residents may see a reduction in the number of agencies utilizing local camera data for investigations. This policy change creates a new internal barrier for how personal travel data is processed and stored within the city.

The takeaway

These changes demonstrate a move toward greater internal control over sensitive surveillance information. Citizens interested in privacy rights should remain aware of how third-party vendors continue to facilitate data sharing independent of direct police-to-police exchanges.
