The Boston Police Department currently has 14 license plate scanners, which are often mounted on police cars.
The Boston Police Department (BPD) has indefinitely halted its use of license plate readers (LPR) following an investigation into their use published on Saturday by the investigative journalism organization MuckRock and the Boston Globe.
David Estrada, a BPD spokesperson, confirmed to Ars that the department had stopped using its LPRs for now and asked that further questions be submitted in writing, which Ars has done.
This suspension likely makes Boston one of the largest cities in America to stop using this sort of technology, which for years has been in wide use by thousands of law enforcement agencies nationwide.
At present, BPD uses 14 individual LPRs, which enables them to scan “as many as 4 million vehicles a year,” the Globe noted.
