When computer hacker Kevin Mitnick arrived at a Calabasas parking garage for a meeting with his friend Lenny DiCicco four weeks ago, DiCicco reached up and casually scratched his head, a prearranged signal to federal agents hiding nearby. Quickly, with the sound of screeching tires and shouted commands, a half dozen men closed in and handcuffed Mitnick. "Len, why did you do this to me?" Mitnick asked as he was being led away, DiCicco recalled later.
