Working to collect vast amounts of data based on license plate readers

Police forces across the United States are quietly investing in vehicle tracking technology that can store vast quantities of data about people's movements, according to the ACLU. The civil liberties group is drawing attention to an interesting 2012 report from the Police Executive Research Forum, which states that 85 percent of police agencies plan to acquire or increase their use of license plate recognition cameras within the next five years.
