Mapp v. Ohio · ¶47

1 am still not persuaded that the Fourth Amendment, standing alone, would be enough to bar the introduction into evidence against an accused of papers and effects seized from him in violation of its commands. For the Fourth Amendment does not itself contain any provision expressly precluding the use of such evidence, and I am extremely doubtful that such a provision could properly be inferred from nothing more than the basic command against unreasonable searches and seizures. Reflection on the problem, however, in the light of cases coming before the Court since Wolf, has led me to conclude that when the Fourth Amendment’s ban against unreasonable searches and seizures is considered together with the Fifth Amendment’s ban against compelled self-incrimination, a constitutional basis emerges which not only justifies but actually requires the exclusionary rule.
