Two Indianapolis City-County Council members are working on a proposal to strengthen oversight of surveillance technology after five current and former IMPD officers were charged with using Flock license plate cameras to track people for personal reasons.

FOX59 reports Councilor Jesse Brown and Council Vice President John Barth are drafting the TRUST ordinance to strengthen oversight of surveillance technology. The proposal would limit data storage to 30 days, require council approval before the city adopts new technology and include reviews of potential privacy risks.

In September, Marion County Prosecutor Ryan Mears announced charges against five officers accused of using the cameras to track romantic partners, spouses and other people. All five face fraud and official misconduct charges, and one officer also faces a stalking charge.

Brown says he has heard concerns about the technology from residents long before the claims involving officers became public. He believes the city needs to thinks about the benefits of surveillance against the potential impact on people’s privacy.

Barth says putting the rules into city law would give them more weight than internal police department policies.

The councilors hope to introduce the ordinance soon and pass it before the end of the year, ahead of the next Indiana legislative session, when lawmakers are expected to discuss license plate cameras.
