JAMES Dale Smith of Chattanooga, US, really wants to be a police officer. He works for a security company, drives a car that looks like a police car, wears a security badge (徽标) that looks like a police badge, and his uniform looks a lot like a real police uniform. Any confusion as to Smith’s real job was cleared up last week when Smith played police officer and attempted to arrest a real police detective (侦探). The detective was in an undercover (秘密的) car, and knew immediately that Smith was not a real cop (警察). Smith has apologized but did admit that he thought the detective was driving too fast. He also asked if he could have his picture taken in the detective’s hat.
