Sterling Heights City Council is calling for greater oversight of the city's Flock license plate reader program. The city operates 24 Flock cameras that capture license plates and vehicle information on passing cars. While police have claimed the technology has been a powerful crime-fighting tool, some council members want to know how the data is being used and who has access to it. Councilmember Michael Radtke Jr. has been critical of the Flock program and is now requesting that the Sterling Heights Police Department hand over a year’s worth of records. The push comes after several residents voiced concerns about the use of the license plate readers and their personal data. Michigan Sen. Jim Runestad has proposed Senate Bill 1131, which would impose strict privacy rules on automatic license plate operators.
