Johnnie Butts allegedly tried selling fake gold jewelry to the wrong man at a suburban Boston supermarket. He offered William Pace a bracelet and a chain marked 14-karat gold for $100. Two problems arose: Pace, who was out of uniform, is the police chief in Randolph, Mass., and he also owns a jewelry store. He could tell the gold was fake by its look and feel. So he arrested Butts on a charge of attempted larceny by false pretense.
