Here the technical progresses made in eaves-dropping technology come in really handy. Eaves-dropping on, let's say, apartments is these days rather trivial and a great way of collecting voice samples of 'suspects'.
That the FBI doesn't have a voice database or at least access to one, I seriously doubt. Most of the technologically advanced countries use voice-recognition already to monitor phone traffic. The US does, Germany does, the UK....
The system functions 'vacuum-cleaner-like' and reacts to voice patterns (individual voices) and trigger words. If a trigger word is said, the entire conversation will be recorded and the telephone number on either end determined for later review.
There are a few books out there, that deal with that kind of thing. Unfortunately, I only remember a german one: "The RAF Phantom", written by three journalists. But an Altavista might bring something up too...
