Which case relates to an individual’s right to remain silent during an investigation?

The case that relates to an individual’s right to remain silent during an investigation is Miranda v. Arizona. This landmark Supreme Court decision established important protections for individuals in custody. The ruling emphasized that individuals have the right to be informed of their rights to remain silent and to have legal counsel present during interrogations. This is commonly known as the "Miranda warning," which ensures that any statements made by a suspect are voluntary and informed.

The decision was grounded in the Fifth Amendment, which protects against self-incrimination, making it clear that without proper advisement of these rights, any statements made by an individual during a custodial interrogation could not be admissible in court. This ruling fundamentally reshaped law enforcement procedures and reinforced the principle that individuals must be aware of their rights when facing police questioning.

The other cases listed do not specifically address the right to remain silent. Frye v. U.S deals with the admissibility of expert testimony, Terry v. Ohio is related to stop-and-frisk procedures and the Fourth Amendment, and Beck v. Ohio discusses the necessity of probable cause for arrest. Each of these cases has its own significance, but none establish the right to remain silent as distinctly as Miranda v. Arizona does.
