We met in the parking lot about half an hour early. When I joined him in his car, he was intently listening to a radio scanner. I didn’t have to ask what he was listening to: the scanner was programmed to pick up all of the frequencies used by the FBI, Secret Service, and U.S. Marshals. And more besides, because when the Feds were dealing with somebody they thought might be wise about technology, they often got tricky and decided to use the frequency of some other agency, like the Bureau of Prisons, or the Drug Enforcement Agency, or even the Postal Inspection Service, among others. So Lewis had those frequencies programmed as well.
