To avoid hassles from local authorities, especially in small towns, a case officer might play Spy Games. It works like this: a completely innocent meeting with a friend will be staged in a local park and made to appear suspicious. He’ll show up late at night, in a trench coat, and carrying bulky envelopes. When police stop to ask what’s going on, he’ll give the officer an unending array of boring details—maybe even tell a few bad jokes. By the time the police leave, they’ll never want to endure such dribble again. They may wave hello, but they’ll never again stop him.
