In 1961, the Supreme Court overturned Mapp’s conviction because

In Mapp v. Ohio (1961), police searched Dollree Mapp’s home without a valid warrant, and the evidence they found was used to convict her. The Supreme Court ruled that evidence obtained through an unconstitutional search could not be used in state court, so it overturned her conviction. Thus, the correct choice is that police did not have a valid reason to search her home.
