The trainees were taking part in a training exercise at a town square Wednesday night in which they were apparently supposed to nab others taking part in the drill. Instead, up to 30 FBI trainees jumped out of a caravan of vehicles and descended on the innocent teen-agers, bound their wrists with plastic ties and ordered them to lie face-down on the sidewalk. After about 30 minutes, the agents set the teens free. The FBI would not comment on the specifics of the drill, but an FBI official apologized Friday and two agents visited the home of one of the youths Thursday night to express their regrets.
