Participation in the prayer was voluntary, but students who left the room or remained silent during the prayer risked being ostracized by their peers for following a different religion or no religion. Michael Angel was a student at a school in Long Island that adopted the prayer in 1958. His father, Steven Angel, joined with several other parents of students in the district to protest the prayer. They argued that the school-sponsored prayer violated the establishment clause of the First Amendment. When the Board of Regents refused to consider their petition to stop the prayer, the group of parents filed suit.
2- The Supreme Court was in favor, the payer did violate the establishment clause. In a 6-1 decision, the Court sided with Engel and the parent group. They said that by providing the prayer, the state of New York had officially approved religion, and the First Amendment prevents government interference with religion. 
3-This case was relevant because the Supreme Court ruled that the establishment clause of the First Amendment, which prevents the government from supporting religion, applied to school-sponsored prayer. The Court prioritized the individual liberty to be free of government interference in religion.

2-The Supreme Court ruled that detained criminal suspects, prior to police questioning, must be informed of their constitutional right to an attorney and against self-incrimination.

3-Was a significant Supreme Court case that ruled that a defendant's statements to authorities are inadmissible in court unless the defendant has been informed of their right to have an attorney present during questioning and an understanding that anything they say will be held against them.

2-The Court did not believe withholding this information was a "service" to the public, thought public had a right to know what government was going (transparent).  The Supreme Court ruled that the First Amendment did protect the right of The New York Times to print the materials. it also determined that the content about the Pentagon Papers had a right to be disseminated.

3-Was a landmark decision of the US Supreme Court ruling that the freedom of speech protections in the First Amendment to the U.S. Constitution restrict the ability of American public officials to sue for defamation.

2-"The Court held that the symbols posed no danger of establishing a state church and that it was "far too late in the day to impose a crabbed reading of the [Establishment] Clause on the country."

3-The display did not violate the Establishment Clause as it had a legitimate secular purpose and is appropriate given the historic importance of religion in public life. Such displays, even where they contain some religious representations, are acceptable under the Establishment Clause so long as do not advance religion or foster excessive entanglement between government and religion. (Lemon test)became a landmark case regarding the separation of church and state; the Establishment Clause outlines the government's role in the separation between church and state.

2-William J. Brennan Jr. wrote the majority decision inferring that all states prohibitions on desecrating the American Flag are invalid. The U.S. Supreme Court ruled in a 5-4 decision in favor of Johnson. The high court agreed that symbolic speech – no matter how offensive to some – is protected under the First Amendment.
3-Texas vs. Johnson is a landmark case since it expressed the definition of the First Amendment and the interpretation which still remains undefined to this day.he Supreme Court struck down on First Amendment grounds a Texas flag desecration law. The 5-4 decision has served as the center point of a continuing debate regarding the value of free speech as exercised through the burning of the U.S. flag as a form of political protest
