Answer:
A. Having obscene books
Explanation:
Mapp v. Ohio, was a landmark case in a criminal proceeding, in which the Supreme Court of the United States decided that evidence obtained in violation of the Fourth Amendment, protects against "unreasonable searches and confiscations."
The Supreme Court of the United States voted 6-3 in favor of Mapp. The court overturned the conviction and five judges held that states were required to exclude evidence seized in violation of the Fourth Amendment. This majority decision applied the rule of exclusion to the states. Judge Potter Stewart, concurring in the result, expressed "no opinion on the merits of the" exclusionary rule, but agreed because Ohio's statute of obscenity, according to which Mapp had been convicted, violated the First Amendment.
