"I don’t have to be constantly stuck on the computer running tags. I can let the cameras do the work for me while I can stay focused on the roads, stay focused on other people driving,” said Trooper Trey Thomas.
Channel 2 Action News worked for months to collect license plate reader – or LPR – data from more than a dozen law enforcement agencies in Georgia. The data can be stored for up to two and a half years, all linked to the seven digits on the backs of people's cars.
