The likely reason the justices ruled as they did in Miranda v. Arizona in 1966 is that they believed that the Fifth Amendment right against self-incrimination was being violated by the police interrogation tactics used in the case. The court held that suspects must be informed of their rights before being interrogated, including the right to remain silent and the right to have an attorney present. This landmark decision established the "Miranda rights" that are now familiar to most Americans and have become a standard part of police procedure. The justices likely believed that these protections were necessary to safeguard individual rights and ensure fair treatment for suspects in the criminal justice system.
