A first booby-trap bomb directed at assassinating Palmer was mailed by anarchists linked to Luigi Galleani . This first bomb was intercepted and defused , but two months later , Palmer and his family narrowly escaped death when an anarchist exploded a bomb on their porch at 2132 R Street , N.W. , Washington D.C . The home of a Department of Justice Bureau of Investigation ( BOI ) field agent Rayme Weston Finch was also attacked . Finch had previously arrested two prominent Galleanists while leading a police raid on the offices of their publication '' Cronaca Sovversiva ''
