Great. But that was just one of the numbers. I wanted to know all of the numbers Pacific Bell Security was using to connect to its secret monitoring boxes. I asked the MLAC lady to look up the original service order that had established the one phone number I had already discovered. As I expected, the order showed that multiple other phone numbers—about thirty of them—had been set up at the same time. And they were originating from what I thought of as the "wiretapping room," where they were recording the intercepts. (Actually, I would find out much later that there was no dedicated wiretapping room; when a call started on any of the lines being monitored, it would be captured on a voice-activated recorder on the desk of whichever security investigator was handling that case, to be listened to whenever he or she had the opportunity.)
