The Geolocation Privacy and Surveillance Act aims to create clear rules for when law enforcement agencies can acquire an individuals geolocation information. It also imposes a fine or imprisonment of up to 10 years for knowingly using a cell-site simulator, except under certain exceptions like a warrant. The Cell Location Privacy Act of 2017 would require law enforcement to obtain a warrant for the use of the technology in emergencies or for foreign intelligence surveillance. The Department of Justice said in September 2015 that law enforcement agents will have to obtain search warrants supported by probable cause.”]
