Examining Law Enforcement Use of Cell Phone Tracking Devices

Examining Law Enforcement Use of Cell Phone Tracking Devices
October 21, 2015
2:00 pm
2154 Rayburn House Office Building


  • To examine issues related to law enforcement’s use of devices that simulate cell phone towers and allow law enforcement to obtain location information for particular suspects.
  • To examine both the Department of Justice’s (DOJ) and the Department of Homeland Security’s (DHS)new policies governing the use of such devices.



  • Media reports have detailed the use of a law enforcement tactic where devices that mimic cell phone towers force cell phones in the area to connect to that device. Once connected, the device gives law enforcement location information about the phone and, presumably, its owner.
  • In April, the Committee sent letters to DOJ and DHS requesting information on the devices.
