Which Supreme Court decision established guidelines for police questioning to protect individuals from self-incrimination?

The Supreme Court decision that established guidelines for police questioning to protect individuals from self-incrimination is Miranda v. Arizona. This landmark case, decided in 1966, focused on the rights of individuals during the police interrogation process. The Court ruled that individuals being taken into custody must be informed of their rights to remain silent and to have legal counsel present during questioning. This decision was pivotal in ensuring that suspects are aware of their Fifth Amendment rights against self-incrimination before any interrogation occurs, thereby aiming to prevent coerced confessions and protect the integrity of the judicial process. The ruling led to the creation of what is commonly known as "Miranda rights," which law enforcement must recite to individuals in custody, reinforcing the principle of protecting personal freedoms in the face of government authority.
