In the United States v. Hale case of 1974, the Supreme Court ruled that a defendant's silence during informal police questioning could be used against him in court. The case revolved around Robert Allen Hale who was convicted for bank robbery based on his evasive and unresponsive behavior during an interrogation by FBI agents. His defense argued that this violated his Fifth Amendment rights to remain silent without it being held as evidence of guilt. However, the Supreme Court disagreed with this argument stating that since he had not been arrested or formally charged at the time of questioning, he did not have any obligation to answer questions and therefore his silence could be seen as suspicious and indicative of guilt.

In the dissenting opinion for United States v. Hale, Justice William O. Douglas argued that the majority's decision undermined a defendant's Fifth Amendment rights against self-incrimination. He contended that by allowing silence during police questioning to be used as evidence of guilt in court, it effectively punished individuals for exercising their constitutional right to remain silent. Furthermore, he believed this ruling could lead law enforcement officers to manipulate suspects into remaining silent so they can later use this silence as an indication of guilt in court proceedings. Justice Douglas also expressed concern about how such a precedent might affect minority and disadvantaged communities who may not fully understand their legal rights or have access to adequate legal counsel.
