Transit police at the Massachusetts Bay Transportation Authority (MBTA) are using music in their fight against crime. The police are playing show tunes and marches at a city subway station in order to drive away large numbers of aggressive teens who used to loiter there after school, reported the Boston Globe. Arresting kids didn't work, but MBTA officials said the music blaring over the newly installed speakers is already reducing crowds at the Forest Hills station, where there had been two to three fights daily. Although several youths have complained about the music, fewer of them are loitering, reported the Globe.
