Step-by-step explanation:
The case that ruled that a person in police custody must be advised of his or her constitutional rights prior to interrogation or the information obtained can be excluded is Miranda v. Arizona.
In this case, the Supreme Court concluded that police often tried to create an atmosphere designed to intimidate or manipulate the accused into confessing. The Miranda decision required a warning to be read to suspects, known as Miranda rights, which include the right to remain silent, the right to have an attorney present, and the right to terminate questioning at any time.
