Mr. Speaker, the threshold is to get subscriber information. The first step when someone gets a call or a threat is to find out who the number belongs to. It used to be very easy. We could pick up a phone book-like thing in the library that had every number in it. It used to be published every year. When somebody called, we could tell where the number came from. The world has changed drastically from that. We are now on VPNs. Even normal office phones are. Land lines do not actually communicate with a direct line. They go over the Internet.
Getting the subscriber information is the first and fundamental step so law enforcement can take subsequent steps to get production orders to tap phones. Those would come after, but the initial step of finding out who is calling, where the information is coming from, is vital.
