Whether a habeas petitioner fairly presents his federal claim in state court

QUESTIONS PRESENTED 1. Whether a habeas petitioner “fairly presents” the “substance” of his federal claim in state court by identifying the relevant facts and the relevant constitutional guarantee, regardless of whether his state-court briefs cited the exact same precedents that he invoked in federal court. 2. Whether Connecticut v. Barrett, 479 U.S. 523 (1987), which held that invocations of Miranda rights must be construed broadly, requires police to stop questioning a suspect who invokes his Fifth Amendment rights by repeatedly stating, “I don’t want to talk” and “I don’t want to talk about this,” even if the invocation is arguably ambiguous in scope.
