On indictment for the refusal to give information requested by the authorized revenue agent, the appellee interposed a special plea averring that it would compel him to become a witness against himself in violation of the Fifth Amendment of the federal Constitution which reads, "nor shall any person be compelled to be a witness against himself." Held, the danger of incrimination in a state court was not grounds for asserting the constitutional privilege. United States v. Murdock, 284 U. S. 141, 52 Sup. Ct. 63, 76 L. ed. 83 (1931).
