it under the cover of the powerful institutions you call order, in the darkness of your laws. There will have to be bloodshed; we will not dodge; there will have to be murder: we will kill, because it is necessary; there will have to be destruction; we will destroy to rid the world of your tyrannical institutions. Police eventually traced a flyer accompanying the bombs to the print shop where Andrea Salsedo, a typesetter, and Roberto Elia, a compositor, were arrested. Salsedo was questioned intensively (some say tortured) by federal agents. After providing some information, he was said to have become increasingly distraught. He died after jumping or being pushed by his compatriot Elia out of the window in the 14th-story room where he was being held. Although Salsedo had admitted he was an anarchist and had printed the flyer, no other arrests for the bombings followed. The police lacked evidence and other Galleanists refused to talk. Elia was deported; according to his lawyer, he turned down an offer to remain in the United States if he would deny his connection to the Galleanists, asserting that his refusal to talk "is my only title of honor". After Valdinoci's death, Coacci and Recchi appeared to have taken more prominent roles in the group; both were bombmakers. Recchi lost his left hand to a premature explosion, but kept making bombs. With the public and the press clamoring for action, US Attorney General Palmer and other government officials began a series of investigations. They used warrantless wiretaps, reviews of subscription records to radical publications, and other measures to investigate thousands of anarchists, communists, and other radicals. With evidence in hand and after agreement with the Immigration Department, the Justice Department arrested thousands in a series of coordinated police actions known as the "Palmer Raids" and deported several hundred of them under the Anarchist Exclusion Act. Following Galleani's deportation and the indictment of Sacco and Vanzetti for murder, more bombings occurred in the U.S. Followers of Galleani, especially Buda, were suspected in the Wall Street bombing of 1920, which killed 38 people and severely wounded 143. In 1927, more bombings were attributed to Galleanists, especially as several court and prison officials were targeted, including Webster Thayer, the trial judge in the Sacco-Vanzetti case. and their executioner, Robert Elliott. In 1932, Thayer was a target again; the front of his house was destroyed by a
