Baird v. United States was a Supreme Court case that addressed the issue of whether a person could be convicted of a crime for refusing to answer questions posed by a grand jury. The case involved a man named William Baird, who was called to testify before a grand jury in the District of Columbia. Baird refused to answer the questions posed to him, citing his Fifth Amendment right against self-incrimination. The government argued that Baird could be convicted of a crime for refusing to answer the questions, and the Supreme Court agreed. The Court held that a person could be convicted of a crime for refusing to answer questions posed by a grand jury, as long as the questions were relevant to the investigation and the person was not being compelled to incriminate himself. The Court also held that the Fifth Amendment did not protect a person from being convicted of a crime for refusing to answer questions posed by a grand jury. This decision has been cited in numerous subsequent cases, and it remains an important precedent in criminal law.

In the case of Baird v. United States, the Supreme Court was asked to decide whether a conviction for selling obscene literature violated the First Amendment right to free speech. The majority opinion held that it did not, but Justice Field dissented from this ruling and argued that such convictions were unconstitutional. He reasoned that obscenity is an expression of ideas and opinions which are protected by the Constitution, regardless of their content or subject matter. Furthermore, he argued that any attempt to limit freedom of speech on moral grounds would be arbitrary and subjective in nature; therefore it should not be allowed under law. In conclusion, Justice Field maintained his belief that punishing someone for expressing their views through obscene material was a violation of constitutional rights and should not be permitted by government authorities.
