The American Civil Liberties Union (ACLU) issued grave concerns this week over the recent revelation that the US Immigrations and Customs Enforcement (ICE) holds a $6.1M contract with Vigilant Solutions, an automatic licence plate reader (ALPR) company. The contract grants ICE access to over 5 billion location records, which include coordinates, time, and date. ALPRs store data for years, making it possible to map out the travel patterns of any and all cars photographed by the machines, and Vigilant Solutions collects ALPR data from the 50 most populated areas of the country. ICE has also been accessing a pool of 1.5 billion records of ALPR data held by local governments.
