Falcone (D) and others sold various essential ingredients of liquor to a group of distillers, knowing that these materials would be used to manufacture liquor illegally. D had no interest in the actual manufacture. The items themselves were legal to sell. Knowledge of the distillers’ criminal purpose was evidenced by the efforts of one of the conspirators to conceal his identity to avoid detection. D was convicted of conspiracy to operate stills. D appealed; they were not a part of the scheme.
