Final answer:
Miranda v. Arizona is a landmark case that established the requirement for police to advise criminal suspects of their rights under the Constitution, known as Miranda rights.
Step-by-step explanation:
Miranda v. Arizona (384 U.S. 436) is a landmark case that ruled that police must advise criminal suspects of their rights under the Constitution, including the right to remain silent, the right to consult with a lawyer, and the right to have one appointed if they cannot afford one. The Miranda decision required a warning to be read to suspects prior to interrogation, known as Miranda rights. This warning ensures that suspects are aware of their rights and can choose whether to exercise them during police questioning.
