With technological advances rendering complex cellular devices increasingly affordable, the majority of the world population is now using smartphones. Further, applications that employ global positioning system (GPS) tracking allow these worldwide smartphone users to take advantage of location-specific information and social networking. In addition, GPS technologies have aided law enforcement agencies in gathering evidence during criminal investigations. However, this convenience, and potential for enhanced public safety, brings the risk of sacrificing the privacy guaranteed to U.S. citizens by the Fourth Amendment protection against unreasonable searches and seizures.
In particular, courts have been concerned with whether a warrant should be required for the government to search cell phones to obtain location data. The statistics regarding police cell phone tracking practices—compiled in an American Civil Liberties Union (ACLU) report—convey the extent and significance of this issue. Of the hundreds of local law enforcement offices surveyed throughout the nation, nearly 95% reported tracking suspects via cell phone GPS data such as international calls, text messages, and emails. Although, some jurisdictions required a search warrant before engaging in this type of GPS tracking, however, some did not. In any event, the applicable legal standards lacked consistency or clarity.
