“In a July 31 amicus brief filed in a federal court in Pennsylvania, the Electronic Frontier Foundation, joined by CDT, ACLU and the ACLU of Pennsylvania, argued that cell phone location information is protected by the Fourth Amendment. The brief argues that a court should require the government to obtain a warrant based on probable cause in order to gain access to cell site location information stored by a cell phone company.”
