After the Nuremberg Trials, Taylor returned to civilian life in the United States, opening a private law practice in New York City. He became increasingly concerned with Senator Joseph McCarthy's activities, which he criticized strongly. In a speech at West Point in 1953, he called McCarthy "a dangerous adventurer," branded his tactics "a vicious weapon of the extreme right against their political opponents," and criticized President Dwight Eisenhower for not stopping McCarthy's "shameful abuse of Congressional investigatory power." He defended several victims of McCarthyism, alleged communists or perjurers, including labor leader Harry Bridges and Junius Scales. Although he lost these two cases (Bridges' sentence of five years in prison was later voided by the Supreme Court, and Scales' six-year sentence was commuted after one year), he remained unfazed by McCarthy's attacks on him, and responded by writing the book, "Grand Inquest: The Story of Congressional Investigations", which was published in 1955.
