The '' Galleanisti '' of Boston held demonstrations , rioted , and committed acts of terrorism . On December 6 , 1916 , the Galleanist Alfonso Fagotti was arrested for stabbing a policeman during a riot in North Square . The next day Galleanists bombed the Salutation Street station of the Boston harbor police . Fagotti was convicted , imprisoned , and later deported to Italy . On June 2 , 1919 , Carlo Valdinoci , a Galleanist from Roxbury , was killed trying to deliver a bomb to U.S. Attorney General A.
