Which case provides the foundation for the exclusionary rule? a. lawrence v. texas b. roe v. wade c. miranda v. arizona d. mapp v. ohio?

D. Mapp vs Ohio was the case that provided the foundation for the Exclusionary Rule. In this landmark case, the Supreme Court decided that evidence obtained in violation of the Fourth Amendment, which protects against "unreasonable searches and seizures", could not be used in state law prosecutions in state courts, as had been established for federal prosecutions. Until this case, most state courts had rejected the Exclusionary Rule.
