On May 23, 1957, in Cleveland, Ohio, three police officers arrived at the home of a Miss Mapp, the appellant. The officers said they had information a bombing suspect was in the house and demanded entry. After telephoning her attorney, she refused to admit them without a search warrant. The officers watched the house until more officers arrived. Three hours later and with four more police officers, they again demanded entrance to the home. When Mapp did not come to the door immediately, a door was forced open and the police entered. At about the same time, Mapp's attorney arrived, but was refused permission to see his client or to enter the home. When Mapp was halfway down the stairs she demanded to see the search warrant. A piece of paper was flashed at her which she grabbed and hid on her person. The officers grabbed her to physically recover the paper. The paper was not a warrant. The police did not find the bombing suspect. However, they did find books and photographs they said were sexually explicit. At trial, the prosecution did not produce a search warrant or prove one was ever issued. Mapp was convicted of violating Ohio state law prohibiting “lewd, lascivious, or obscene material.” She was sentenced to one to seven years in prison. Mapp appealed the conviction based on her First Amendment rights.
