Abstract

Mapp v. Ohio: A Landmark Case in Cleveland History is a digital exhibit which includes case documents, audio files, photographs, summaries and news articles. The exhibit covers the case from the underlying facts to the United States Supreme Court decision, 367 U.S. 643 (1961). The U.S. Supreme Court held that the exclusionary rule applied to the states. The exclusionary rule holds that evidence obtained in violation of defendant's Fourth Amendment rights, such as evidence obtained without a warrant as required by the Fourth Amendment, must be excluded as evidence in the defendant's criminal trial.
