Miranda v. Arizona is significant for establishing which right?

Miranda v. Arizona is a landmark Supreme Court case that established the requirement for law enforcement to inform individuals of their rights prior to interrogation, specifically the 5th Amendment right against self-incrimination. This decision underscores that individuals must be made aware of their rights to remain silent and to have an attorney present during questioning to ensure that any statements made are voluntarily and knowingly given.

The ruling came in response to concerns that suspects were often unaware of their rights, leading to coerced confessions and unfair trials. By establishing this requirement, the Miranda decision was aimed at protecting the integrity of the judicial process and ensuring that defendants are aware of their rights under the Constitution.

This case does not address the rights related to free speech, unreasonable search and seizure, or the right to an impartial trial, which are protected by different amendments and legal precedents. Miranda v. Arizona specifically focuses on the rights of individuals during police interrogations, making the 5th Amendment right against self-incrimination the correct answer.
