United States v. Eichman, 496 U.S. 310 (1990) was a United States Supreme Court case that invalidated a federal law against flag desecration as violating of free speech under the First Amendment.
 It was argued together with the case "United States v. Haggerty".
 It built on the opinion handed down in the Court's decision the prior year in "Texas v. Johnson" (1989), which invalidated on First Amendment grounds a Texas state statute banning flag-burning.
Patterson v. Colorado, 205 U.S. 454 (1907) , was a First Amendment case.
 Before 1919, the primary legal test used in the United States to determine if speech could be criminalized was the bad tendency test.
 Rooted in English common law, the test permitted speech to be outlawed if it had a tendency to harm public welfare.
 One of the earliest cases the Supreme Court heard addressing punishment after material was published was 1907's "Patterson v. Colorado" in which the Court used the bad tendency test to uphold contempt charges against a newspaper publisher who accused Colorado judges of acting on behalf of local utility companies.
Barnes v. Glen Theatre, Inc., 501 U.S. 560 (1991) , is a landmark decision of the Supreme Court of the United States concerning the First Amendment and the ability of the government to outlaw certain forms of expressive conduct.
 It ruled that the state has the constitutional authority to ban public nudity, even as part of expressive conduct such as dancing, because it furthers a substantial government interest in protecting the morality and order of society.
 This case is perhaps best summarized by a sentence in Justice Souter's concurring opinion, which is often paraphrased as "Nudity itself is not inherently expressive conduct."
During the tenure of Morrison Waite as Chief Justice of the Supreme Court of the United States (March 4, 1874 through March 23, 1888), the Supreme Court heard an unprecedented volume and frequency of criminal cases.
 In just fourteen years, the Court heard 106 criminal cases, almost as many cases as the Supreme Court had heard in the period from its creation to the appointment of Waite as Chief Justice.
 Notable cases include "United States v. Cruikshank" (1875), "United States v. Reese" (1875), "Reynolds v. United States" (1878), "Wilkerson v. Utah" (1879), the "Trade-Mark Cases" (1879), "Strauder v. West Virginia" (1880), "Pace v. Alabama" (1883), "United States v. Harris" (1883), "Ex parte Crow Dog" (1883), "Hurtado v. California" (1884), "Clawson v. United States" (1885), "Yick Wo v. Hopkins" (1886), "United States v. Kagama" (1886), "Ker v. Illinois" (1886), and "Mugler v. Kansas" (1887).
Virginia v. Black, 538 U.S. 343 (2003) , is a First Amendment case decided in the Supreme Court of the United States.
 Three defendants were convicted in two separate cases of violating a Virginia statute against cross burning.
 In this case, the Court struck down that statute to the extent that it considered cross burning as "prima facie" evidence of intent to intimidate.
 Such a provision, the Court argued, blurs the distinction between proscribable "threats of intimidation" and the Ku Klux Klan's protected "messages of shared ideology."
 However, cross-burning can be a criminal offense if the intent to intimidate is proven.
The Dixon School Case (Zellers v. Huff) was a lawsuit started in 1948 in New Mexico contesting the use of nuns, religious brothers and priests as teachers in publicly supported schools under the First Amendment to the United States Constitution.
 The case involved thirty schools in eleven New Mexico counties, twenty-eight plaintiffs, two hundred defendants, and public expenditures to the schools of over $600,000 annually.
 Following on the heels of the U.S. Supreme Court's decision in "Everson v. Board of Education", which applied First Amendment freedoms to state as well as federal law, the Dixon School Case was the first state case to implement separation of church and state in public schools, and was watched with interest nationally.
Kahle v. Gonzales (previously named "Kahle v. Ashcroft") is a First Amendment case that challenges the change in the copyright system of the United States from an opt-in system to an opt-out system.
Reynolds v. United States, 98 U.S. (8 Otto.)
 145 (1878), was a Supreme Court of the United States case that held that religious duty was not a defense to a criminal indictment.
 "Reynolds" was the first Supreme Court opinion to address the Impartial Jury and the Confrontation Clauses of the Sixth Amendment.
Barnes v. Yahoo!, Inc., 570 F. 3d 1096 (D. Or.
 Nov. 8, 2005), is a United States Court of Appeals for the Ninth Circuit case in which the Ninth Circuit held that Section 230 of the Communications Decency Act (CDA) rules that Yahoo!, Inc., as an Internet service provider cannot be held responsible for failure to remove objectionable content posted to their website by a third party.
 Plaintiff Cecilia Barnes made claims arising out of Defendant Yahoo!, Inc.'s alleged failure to honor promises to remove offensive content about the plaintiff posted by a third party.
 The content consisted of a personal profile with nude photos of the Plaintiff and her contact information.
 The United States District Court for the District of Oregon had dismissed Barnes' complaint.
Freedom for the Thought That We Hate: A Biography of the First Amendment is a 2007 non-fiction book by journalist Anthony Lewis about freedom of speech, freedom of the press, freedom of thought, and the First Amendment to the United States Constitution.
 The book starts by quoting the First Amendment, which prohibits the U.S. Congress from creating legislation which limits free speech or freedom of the press.
 Lewis traces the evolution of civil liberties in the U.S. through key historical events.
 He provides an overview of important free speech case law, including U.S. Supreme Court opinions in "Schenck v. United States" (1919), "Whitney v. California" (1927), "United States v. Schwimmer" (1929), "New York Times Co. v. Sullivan" (1964), and "New York Times Co. v. United States" (1971).
