New e-mails reveal Feds not "forthright" about fake cell tower devices

According to new Justice Department e-mails obtained by the American Civil Liberties Union (ACLU) of Northern California, and published on Wednesday, federal investigators have been routinely using “stingrays” to catch bad guys. A stingray is a device that can create a false cellphone tower, and allows authorities to determine a particular mobile phone’s precise location. Stingrays aren’t new—law enforcement agencies nationwide are believed to have been using them for years.
