On May 23, 1957, police officers in a Cleveland, Ohio suburb received information that a suspect of a bombing case, as well as some illegal betting equipment, might be found in the home of Dollree Mapp. Three officers went to the home and asked for permission to enter, but Mapp refused to let them in without a search warrant. Two officers left, and one remained. Three hours later, the two returned with several other officers with a piece of paper and broke in the door.
