A Michigan lawmaker is planning to introduce legislation to regulate the use of devices that photograph license plates.
Rep. Sam Singh says his upcoming bill would require police agencies to delete license plate records from data systems within 48 hours unless the record is evidence of specific criminal wrongdoing.
The East Lansing Democrat said last week that innovative law enforcement ideas are needed to keep the public safe. But Singh says "a vast, unbridled data collection system cannot be tolerated in this state."
Authorities say the devices help identify stolen cars and drivers with outstanding warrants.
Singh said his bill comes in the wake of concerns over personal privacy and revelations of federal domestic spying programs.
Similar legislation has been proposed in Maine, New Hampshire, Virginia and Vermont.
