Answer:
D. Leyra v. Denno.
Step-by-step explanation:
Leya v. Deno was a case where an individual suspected of murder was subjected to many hours of interrogation with a skilled and manipulative psychiatrist who managed to get a confession out of him that convicted him of murder. This psychiatrist was presented to the accused as a doctor who would bring more comfort to the interrogation process, however, the psychiatrist was using psychological methods, threats, promises and other subterfuges. Once the confession was made and the candidate was convicted, the State Court of Appeals revoked the conviction on the grounds that the accused was manipulated and the confession was forced.
This created a question about the veracity of the methods used in interrogations in the country, resulting in the prohibition of police departments in hiring qualified professionals in the art of manipulation.
