Miranda v. Arizona, 384 U.S. 436 (1966) was a landmark decision of the U.S. Supreme Court, which ruled that law enforcement must warn a person of their constitutional rights before interrogating them, specifically under the Fifth Amendment, which states that people cannot be forced to be a witness against themselves. The case of Ernesto Miranda, who was accused of a serious crime, brought this about. The police did not inform him of his right to remain silent or his right to an attorney, and he was interrogated for two hours, after which he confessed to the crime and was convicted. The U.S. Supreme Court decided to accept the case, and Chief Justice Earl Warren announced the decision in 1966, stating that police must warn criminal suspects about their rights to silence and legal counsel before interrogation, otherwise any confession may be challenged and thrown out.

The Fifth Amendment
The case of Miranda vs. Arizona (1966) is a landmark decision by the U.S. Supreme Court, which ruled that law enforcement must inform individuals of their constitutional rights before interrogation, specifically their Miranda rights. This ruling was based on the Fifth Amendment to the U.S. Constitution, which protects individuals from self-incrimination.
The Miranda vs. Arizona case established the importance of the Fifth Amendment in protecting the rights of individuals during police custody. The ruling ensured that suspects are informed of their Miranda rights, which include the right to remain silent and the right to an attorney. This was a significant change in American criminal law, as previously, the Fifth Amendment was understood to protect only against formal types of compulsion to confess.
The impact of the Miranda ruling extended beyond the specific case and became a routine part of police procedure in the United States. Law enforcement agencies adopted the practice of "Mirandizing," ensuring that suspects were informed of their rights before interrogation. The case set a precedent for how law enforcement agencies across the country conducted interrogations and protected the rights of individuals during police custody.
However, the Miranda ruling has also been challenged and undermined by subsequent decisions that granted exceptions to the Miranda warnings. For example, in Harris v. New York (1971), the Court held that a confession obtained in violation of Miranda standards could be used to impeach the defendant's testimony. Additionally, in Rhode Island v. Innis (1980), the Court held that a "spontaneous" statement made by a defendant in custody without Miranda warnings was admissible as evidence. Despite these exceptions, the Miranda vs. Arizona case remains a significant moment in the history of American criminal law, upholding the Fifth Amendment rights of individuals during police interrogations.
