Civil Liberties Groups Oppose Government Mobile Phone Tracking

Three civil liberties groups have asked a US appeals court to strike down a US government request to obtain stored mobile phone location tracking information without showing probable cause. The Electronic Frontier Foundation (EFF), the Center for Democracy and Technology (CDT) and the American Civil Liberties Union (ACLU) have filed a brief asking the US 3rd Circuit Court of Appeals to reject the US Department of Justice’s request that courts give permission for it to obtain historical mobile-phone tracking information without a court-ordered warrant showing probable cause
