Doyle v. Ohio

Providing a constitutional protection to a defendant and then using that protection against them renders the protection meaningless. The Court stated that “while it is true that the Miranda warnings contain no express assurance that silence will carry no penalty, such assurance is implicit to any person who receives the warnings. In such circumstances, it would be fundamentally unfair and a deprivation of due process to allow the arrested person’s silence to be used to impeach an explanation subsequently offered at trial.”
