"shall furnish agents from the Federal Bureau of Investigation, forthwith , all information, facilities, and technical assistance necessary to accomplish the installation and use of the pen/trap device."

Before, they would really demand only the information of the user named in the court order. This time it was "just let us install this thing inside and don't ask."
