Fighting a Striking Case of Warrantless Cell Phone Tracking

Fighting a Striking Case of Warrantless Cell Phone Tracking

By Bennett Stein, ACLU Speech, Privacy and Technology Project at 4:16pm
The Fourth Circuit Court of Appeals is currently considering a case that could be pivotal in determining whether the government needs a warrant to track your cell phone. Today the ACLU, together with the ACLU of Maryland, Center for Democracy & Technology, Electronic Frontier Foundation, and National Association of Criminal Defense Lawyers, filed an amicus brief arguing that the Fourth Amendment requires the government get a warrant to find out everywhere a person has been for the past seven months. In the case, United States v. Graham, the government obtained a staggering 221 days of historical cell site location information for two suspects. For one suspect, Aaron Graham, this timespan allowed the government to sweep up his location at 29,659 specific points. (You can see our brief here, and see here a document we filed that shows all of Sprint's cell sites in the Baltimore area.)
